It is important to choose the right meter for the application or parameter being analysed.
Mobile gas detectors
Would you like to use mobile gas detectors to detect specific sources of danger in an industrial environment? HeylNeomeris offers you the right sensor for your area of application.
Mobile gas detectors are used in companies to measure potentially hazardous gas concentrations in the air and detect them at an early stage. They are used to protect employees, the environment and to comply with safety standards.
The detectors are portable devices that can be carried by employees as required. They are battery-operated and have sensors that can detect different types of gases such as ozone, methane, hydrogen, etc.
Companies throughout Germany use mobile gas detectors in various areas, depending on the specific sources of danger. Mobile gas detectors are used, for example, in industrial plants. In factories and production facilities, the use of mobile gas detectors enables the detection of leaks or unusual gas concentrations in pipes, tanks or other systems.
The detectors can trigger audible and visual alarms if a dangerous gas concentration is detected. This allows employees to react quickly and take appropriate action, such as evacuating the area or shutting down equipment.
You can find a selection of our products (sensors and measuring devices) in our online shop under Gas measuring devices - Heyl Neomeris Shop

Ozone generators
HeylNeomeris as your supplier for ozone generators - equipment technology for the disinfection of water and air as well as for the purification of process water in industry
Ozone generators are used to produce ozone and are extremely powerful and efficient. They are an important component of water treatment and in industry. Ozone generators are used in industrial water treatment, process water treatment and, in particular, in the pharmaceutical industry, where they are used to kill germs and disinfect water and air. Ozone generators therefore enable the disinfection of drinking water and swimming pool water, for example. The advantage of using ozone is its environmental friendliness, the short dwell time in the water and its neutral flavour.
You can find a selection of ozone generators in the HeylNeomeris product portfolio at Ozone and UV technology - Heyl Neomeris Shop .
If you have any questions, you can contact us by phone, e-mail or via our contact form. We look forward to your enquiry.
Residual ozone destroyer
Residual ozone destructors from HeylNeomeris for the reduction of excess ozone
Residual ozone destructors are devices that are used in water treatment to break down excess ozone. Ozone is a reactive gas that can be produced in the atmosphere as well as by some devices such as ozone generators. Ozone destructors destroy the ozone produced before it can be released into the environment.
They work by catalytic decomposition of ozone using special catalysts. Our system consists of a reactor housing, flow internals and droplet separators, Carulite 200 catalyst granulate and electrical trace heating. HeylNeomeris is a supplier of residual ozone neutralisers and offers you a broad product portfolio of catalytic residual ozone neutralisers.

UV systems
HeylNeomeris as an expert and supplier of UV systems
UV systems are used in water treatment to kill microorganisms such as bacteria, viruses, yeasts and parasites.The systems work by irradiating the water with ultraviolet light, which destroys the organisms' DNA and RNA and thus prevents them from reproducing. UV disinfection is an effective method of water treatment as it requires no chemical additives and produces no harmful by-products.
UV systems are ideal for monitoring the water quality of water treatment, water blending and drinking water systems.They are easy to install and maintain.However, a precise technical design of the UV system is required to ensure that the UV disinfection does not fail to be effective and that the number of microorganisms is reduced to the desired minimum.
The quality and safety of drinking and process water can be guaranteed with a UV system.You can find a selection of our range of UV systems at UV systems - Heyl Neomeris Shop. In the product area, you will find products for different areas of application. If you have any questions or need advice, please contact us by phone or e-mail.
Calibration solutions
Calibration solutions are used to calibrate measuring instruments to a known reference to ensure that they provide accurate measurements.
HeylNeomeris offers a broad product portfolio of calibration solutions that are used in a wide range of applications, such as analytical chemistry, biochemistry, medicine, environmental analysis and the food industry.
There are various calibration methods for calibrating measuring devices.
A one-point calibration is a calibration method in which a measuring device is calibrated to a known reference by adjusting it to a solution with a known value. A two-point calibration is a calibration method in which a measuring device is calibrated to two known references by adapting it to solutions with two known values.
In one-point calibration, the meter is calibrated to a single point, while in two-point calibration, the meter is calibrated to two points. One-point calibration is easier and faster than two-point calibration, but two-point calibration is more accurate and reliable.
We offer a wide range of calibration solutions in different bottle sizes and disposable bags.

Buffer solutions
Buffer solutions are solutions that keep the pH value stable when acids or bases are added. Buffer solutions are used, for example, in biochemistry, analytical chemistry or formulation.
The HeylNeomeris product portfolio offers a wide range of buffer solutions.
Examples include redox buffer solutions, which are used to keep the redox potential of a sample constant. A redox buffer consists of a redox pair consisting of an oxidation and a reduction component, which are mixed in a specific concentration to generate a defined redox potential. Buffer solutions therefore consist of a conjugate acid-base pair and can keep the pH value of a solution relatively stable. Redox buffer solutions are often used in biochemistry. They ensure that reactions take place at a constant pH value.
Another example of buffer solutions from our HeylNeomeris range are the pH buffer solutions. The pH value is an important parameter when analysing water. It indicates whether a solution is acidic, neutral or alkaline. In pure water or in neutral solutions, the pH value is 7. A pH value below 7 indicates an acidic solution, while a pH value above 7 indicates an alkaline solution. In water analysis, the pH value is measured to determine the quality of the water. The pH value is an important parameter in many technical systems, especially in water treatment. The pH value influences the chemical reactions that take place in the systems and can therefore affect the efficiency of the systems. For example, a pH value that is too low can lead to malfunctions in wastewater treatment plants, as it inhibits the growth of microorganisms that are responsible for the decomposition of organic substances. A pH value that is too high can lead to deposits and corrosion in pipework and other system components. In heating systems, a pH value that is too low can lead to corrosion and damage to the systems. In agriculture, a soil pH value that is too low can impair the growth of plants.
Choose the buffer solutions for your area of application from our comprehensive range, which are available in different bottle sizes or disposable bags.
Stationary gas detectors
HeylNeomeris as your supplier for stationary gas detectors - for measuring gas concentrations and for continuous ozone measurement
Stationary gas detectors are used in companies to ensure the safety of employees and systems. They measure the concentration of gases such as toxic gases, oxygen deficiency, flammable gases and vapours that cannot be detected by the human senses. The detectors alert the worker at an early stage and increase occupational safety.
Stationary measuring devices can be used for continuous ozone measurement in manufacturing companies. They measure the ozone concentration in the air in rooms with ozone generators, residual ozone destructors and ozone treatment systems.
Our ozone measurement device is the Gasmaster III, which is small, robust and ergonomic.

Tradition and future for innovative Water treatment plants Wuppertal
Water treatment Wuppertal with state-of-the-art measurement, control and regulation technology
Wuppertal is decentralized – and more than “just” a city. With 355,000 inhabitants, it ranks 17th among Germany’s largest cities. In principle, however, it consists of the two former major cities of Barmen and Elberfeld plus the ex-towns and communities of Cronenberg, Ronsdorf, Beyenburg, Vohwinkel, Sonnborn and Langerfeld. They were united to form a single municipality only in 1929.
The city is characterized by the narrow valley of the Wupper River, which gives it its name, as well as residential areas on steep slopes. Due to the narrowness of the valley, it was decided around 1900 not to build a tramway and to build the world-famous suspension railroad. Numerous pumps and water towers are necessary for the drinking water supply. Indispensable for the drinking water quality is precise, state-of-the-art measurement, control and regulation technology for the water treatment Wuppertal.
The individual cities and communities had already developed their own drinking water supply networks long before unification in 1929. As a result, Wuppertal still draws its drinking water from three very different sources. In the water supply network, the respective self-sufficient structures of old can still be recognized. Incidentally, the total length of Wuppertal’s water pipelines is 1,200 kilometers. This is almost equivalent to the distance between Wuppertal and Naples.

Data and facts about water treatment Wuppertal
Data and facts on water treatment Wuppertal
Another reason for the different sources of drinking water is that the local Wupper River was no longer suitable for drawing water from bank filtrates as early as the mid-19th century. Textile and chemical industries polluted the water too much and endangered health and hygiene. Ergo, the cities and communities of today’s Wuppertal created new concepts for water extraction and treatment using the latest measurement and control technology of their time.
The city of Elberfeld opened its first municipal waterworks in 1879. However, it was located in Benrath, which is now a district on the southern edge of Düsseldorf. Here, mainly Rhine bank filtrate is still processed into drinking water for Vohwinkel and Elberfeld-West. With 8.7 million cubic meters, the Benrath waterworks supplies about one-third of the total drinking water for Wuppertal.
Where does Wuppertal’s drinking water come from?
The east of Wuppertal receives its water from the Herbringhauser dam, completed in 1900, and the Kerspetalsperre, built in 1912. The water from both reservoirs is treated at the Herbringhausen waterworks and brought here, pun intended. The annual volume is about six million cubic meters. The third main source of water for Wuppertal dates back to the late 1950s: the Dhünntalsperre. In 1978, it was expanded almost tenfold to become the Great Dhünntalsperre. The city draws around 12 million cubic meters of drinking water from it every year, which is treated at the Dabringhausen waterworks.
The Wuppertal waterworks use different water treatment techniques, as the dam water and the Rhine bank filtrate have different raw water values and differ greatly in terms of their basic composition. Here as well as there, the most modern and precise measuring devices as well as high-tech control and regulation technology are used, as offered by Neomeris from Hildesheim. This ensures that the Wuppertal water treatment plant meets all the standards and regulations of the German Drinking Water Ordinance.
The Bergisches Land region is very rich in rain and snow. At the reservoirs, annual precipitation can be twice as high as in the city. In the surrounding area, water protection areas are spreading out, which are used in an environmentally friendly way in cooperation with local farmers.
Water treatment in Wuppertal: sources, technologies and environmental protection
Water treatment in Wuppertal: sources, technologies and environmental protection
The Herbringhausen and Dabringhausen waterworks operate in a similar way, as the raw water from both dams is of almost identical quality. In micro-screening plants, the coarse foreign matter is removed with stainless steel net filters. After adding a flocculant, the fine turbid matter is deposited in larger flakes. These are removed in the first filter stages by means of two coarse filters. Subsequently, the treated water is ozonated in order to disinfect it. The ozone required for this is generated on site by ozone generators and the required concentration is permanently monitored by sensors. Heyl-Neomeris also offers the complete range of the necessary plant technology for this area.
The second filter stages of both waterworks remove the reaction products of ozonation with activated carbon filters. Precise ozone measurement technology ensures reliable control. This is followed in each case by a third filter stage with natural limestone filter. Here the water is freed from excess carbonic acid. The final stage of water treatment Wuppertal in these two waterworks is disinfection with chlorine dioxide, which can be monitored, for example, by state-of-the-art sensory or wet-chemical analysis technology from Heyl-Neomeris.
Drinking water treatment of reservoir water and Rhine bank filtrate
The situation is different in Benrath. The Rhine bank filtrate there is extracted from deep wells and enriched with onshore groundwater from a nature reserve on the left bank of the Rhine. The waterworks was recently extensively modernized and went back into operation in 2019 with the latest control, measurement and regulation technology.
Since then, water treatment has been running with a new deacidification plant and top-modernized softening plant with the latest water hardness measurement technology. Also renewed: the process control technology with its system solutions for process monitoring. Finally, new pipes were laid and new fittings installed. The Benrath waterworks thus stands for the healthiest and most efficient water treatment with the latest technology (source: WSW Wuppertaler Stadtwerke).
In addition to drinking water, process water is also treated and ultrapure water is produced for large cities like Wuppertal. Process water or cooling water supplies industrial plants or power stations. Ultrapure water does not contain any foreign substances. It is needed in food, semiconductor and pharmaceutical production. Every form of water treatment requires the most precise analysis, measurement and control technology as well as control equipment.
