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.

Tradition and future for innovative Water treatment plants Hanover
Innovative measurement technology for water treatment plants, Hanover
Reliable measurement and control technology, as well as systems for disinfection, play an essential role in improving the use and exploitation of water as a resource. Modern water treatment plants use sophisticated systems and processes that only work with reliable measurement technology and control engineering. The public water supply in Germany is subject to precisely defined standards in DIN 2000 and 2001. These specify, among other things, the requirements for drinking water as well as for the planning, construction and operation of supply and water water treatment plants are described.
Components of water treatment plants
Water hardness measurement is a fundamental component in almost every wastewater treatment plant.
The reverse osmosis is a filtration process in which water is forced through a membrane. In the process, the dirt particles are
the membrane, and the purified water is collected and
collected and reused.
To ensure the required water quality in the process water, depending on the raw water quality, water treatment (filtration, softening, desalination, etc.) must be carried out. Ultrapure water is becoming more and more standard in the beverage and food industries.

Germ-free water through water treatment plants
Germ-free water through water treatment systems
A similarly high standard of purification often applies to service water as to the pipes themselves.Here, too, there must be no germs.
The pure water is required for very sensitive production areas, such as in medical technology,in clinics, in the pharmaceutical and food industries, and in semiconductor production.
The production of ultrapure water is very complex. The elimination of foreign substances in the water makes constant differentiated monitoring necessary.
The pharmaceutical industry has particularly high standards for treated water, also called pharma water. High quality requirements demand a great deal of effort on the measuring technology in the water treatment plant.
The treatment of private and industrial wastewater is carried out in three stages. Especially due to micro-pollutants, e.g. by pharmaceutical substances, a fourth stage becomes more and more necessary to guarantee the water quality.
Regulations for drinking water in water treatment plants also in Hanover
Regulations for drinking water in water treatment plants also in Hannover
The hygienic requirements for drinking water, bathing water and process water (e.g. cooling water) are described and regulated in various guidelines, ordinances and laws.
These regulations must be observed and complied with in a water treatment plant.
According to the drinking water ordinance, only the approved chemicals chlorine gas, sodium and calcium hypochlorite, chlorine dioxide and ozone as well as UV irradiation may be used for disinfection in water treatment plants at present. Chlorination, both by means of chlorine gas or hypochlorite dosing, is the most frequently used disinfection process in water treatment, mainly because of its depot effect and the associated low risk of recontamination ,.
The microbiological effect of chlorination by hypochlorous acid is strongly pH-dependent and thus in practice often requires a correction of the pH value by acid addition in the water treatment plant. The amount of chlorine-containing product to be dosed depends on the chlorine consumption in the water and the disinfection requirements, which may vary depending on the application.
Regulations of cooling water in water treatment plants
In the treatment of cooling water , both in once-through cooling systems- and in open circuits, effective elimination of microorganisms, especially to reduce biofilm formation and avoid Legionella, is taken into account.The use and proper application of biocides is subject to the EU Biocide Regulation and the GefStoffV (see details and notes in VDI 2047_2).
Oxidizing biocides based on inorganic or organic chlorine compounds are often used, the effectiveness of which against Legionella must be tested in accordance with DIN EN 13623.
Quotation from VDI 2047-2 :
“For oxidative biocides, continuous monitoring is possible. As a control variable for the dosage, amperometric or direct photometric measurement methods can be used. The measurement of the redox potential is only suitable as a monitoring parameter. For discontinuous measurement, the DPD method according to DIN 38408 has proven itself”.
The DPD (N,N-diethyl-p-phenylenediamine) method according to DIN EN ISO 7393-2 (formerly DIN 38408) is recognized and approved worldwide for photometric chlorine determination.
The method is based on the formation of a red dye from the reaction of DPD with chlorine in aqueous medium at pH 6-7. The optical adsorption is directly proportional to the dye concentration present or the amount of free chlorine present.
To subsequently determine the total chlorine content, use the addition of potassium iodide (KJ):
In the sample, the chlorine substitution products release a stoichiometric amount of iodine, which reacts with the DPD instead of the chlorine. The total chlorine content is thus determined from the dye intensity formed. The combined chlorine (mainly chloramines) results from the difference of total chlorine and free chlorine.
