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.

Tradition and future for innovative Water treatment plants Düsseldorf
Measurement and control technology for water treatment, Düsseldorf
Water treatment for a major city like Düsseldorf is unthinkable without the precision of reliable control technology, measurement technology and regulation technology. Neomeris from Hildesheim specializes in high-tech equipment for the treatment of drinking water, ultra-pure water or process water. Also for “Rhine water”. Because:
Alt beer may flow in streams at the longest bar in the world. The people of Düsseldorf consume much more drinking water from the “longest tap in the city” and do so much more frequently. With a population of over 620,000, the capital of North Rhine-Westphalia is Germany’s seventh largest city. More than 1,800 kilometers of water pipes supply people and businesses in Düsseldorf and the neighboring cities of Mettmann and Erkrath. On average, Düsseldorfers consume 122 liters of drinking water a day. On hot summer days, up to 250,000 cubic meters of drinking water flow through the pipes into households, industrial and commercial enterprises, and gardens and green spaces.
Drinking water for Düsseldorf: water treatment on the Rhine
But where does Düsseldorf’s drinking water come from? Stadtwerke Düsseldorf obtains around three-quarters of its drinking water from percolating Rhine water. About a quarter comes from groundwater. The Rhine is therefore the most important resource.
It takes about 27 days for the Rhine water to reach the castle tower from its source at an altitude of more than 2,300 meters in the Swiss Alpine canton of Graubünden. Large parts of it seep into the bottom of the river as so-called bank filtrate. For several weeks, the raw water flows through layers of gravel and sand up to 30 meters thick and undergoes a natural purification process. Sand and gravel as well as microorganisms in the soil already filter out a large part of the dirt, pollutants and turbidity from the water. Only then is the bank filtrate, together with the groundwater, pumped into the municipal wells and finally fed into the four water treatment plants Flehe, Holthausen, Am Staad and Lörick.

The "Düsseldorf process" for the treatment of drinking water
The “Düsseldorf process” for water treatment of drinking water
Water treatment is carried out in the four waterworks according to the so-called “Düsseldorf process”. It was developed back in the 1950s. In the first step, the waterworks add ozone to the raw water to purify and disinfect it. Step two is storage in tanks where the water continues to react with the ozone for an extended period of time, continuing the purification process. In the third step, waterworks workers pump the water through layers of activated carbon. Here, organic chlorine compounds, odors, flavors and other undesirable substances are filtered out.
What remains is clean drinking water with healthy levels of potassium, calcium and magnesium. Seen in this light, no Düsseldorfers would actually need to buy bottles of mineral water. Every day, Stadtwerke Düsseldorf checks its water according to the strictest criteria. It meets all the requirements of the German Drinking Water Ordinance (TrinkwV), DIN 2000 and the General Ordinance for the Supply of Water (AVBWasserV). Düsseldorf’s drinking water is also suitable for preparing baby food. With an average hardness level of 13.9 °dH (German hardness), Düsseldorf’s drinking water is classified as hard (source: Stadtwerke Düsseldorf AG).
In short: It is a long way from natural Rhine water to healthy, drinkable “pure water”. State-of-the-art control, measurement and regulation technology is the guarantee for thorough water treatment.
Water treatment plants with Neomeris measurement and control technology
Water treatment plants with Neomeris measurement and control technology
The “Düsseldorf process” for water treatment of drinking water is a special feature. More commonly, water treatment plants consist of a softening plant, a reverse osmosis plant, a permeate tank and a pressure boost. For these steps, Neomeris provides the necessary high-precision control, measurement and regulation technology.
In all natural raw water, saline hardness constituents are dissolved. For the most part, these are compounds with calcium and magnesium. The ion exchange process is used for softening. In simple terms, calcium and magnesium are removed from the water using a special resin. The water is passed over the resin, which absorbs calcium and magnesium and releases sodium in return.
State-of-the-art water hardness meters are used to reliably monitor the exchange. When the resin is exhausted, the so-called regeneration of the softening plant is initiated by means of the latest measuring technology. To ensure an uninterrupted supply, such plants are always designed with at least redundancy. If one stage is exhausted, a second stage takes over the softening.
The reverse osmosis plant carries out the next process of water treatment. At its core is a fine membrane. On one side of this “filter” is water with a higher concentration of foreign substances, and on the other side is water with a low foreign substance content. Under natural circumstances, a concentration balance would now occur, with this occurring from the side with the lower concentration to the side with the higher concentration. This natural behavior is also called osmotic pressure. This equalization occurs until equilibrium is reached. As the name implies, the process reverses this natural process. By means of an artificial pressure generated by pumps on the raw water side, the water molecules are forced through the membrane. Unwanted dissolved substances, are held back at the mebrane due to their molecular size. At the end of the process, up to 95 percent of all foreign substances can be removed from the water with the aid of state-of-the-art control technology and measuring and control equipment. Higher purity levels, which are required for example in pharmaceutical applications or in the semiconductor industry, can be achieved by using additional downstream processes such as electrodeionization.
Next stations on the way to drinking water or ultrapure water are the permeate tank and pressure boosting for delivery to the mains.
Process water and ultrapure water for the Rhine metropolis
Düsseldorf needs more than just drinking water. The so-called process water supplies industrial plants and power stations. Strict cleanliness requirements also apply here. The ultra-pure water must even be almost completely free of foreign substances, as it is needed for the production of beverages or medicine, among other things.
