Precise measurement reliability in industry standard for water treatment plants
Measurement technology for water treatment plants is our expertise.
NEOMERIS is an umbrella brand of Gebrüder Heyl Vertriebsgesellschaft für innovative Wasseraufbereitung mbH.
For over 60 years, our parent company, Gebrüder Heyl Analysentechnik GmbH & Co.KG, has been a specialist in industrial water treatment.
In production of our parent company analysis, measuring and control devices for water treatment are developed and produced. This includes e.g. test automats and control systems.
In addition, UV systems, electrolytic ozone generators, multiparameter handheld photometers, pocket testers and conductivity meters are sold through our umbrella brand.
The Testomat series measures more than 20 parameters, including water hardness, carbonate hardness, free chlorine and chlorine dioxide. The instruments are used in a wide range of applications, including drinking water treatment, swimming pools, food production, cooling, heating and water circuits, legionella prophylaxis, industrial applications and wastewater treatment.
The company is the market leader in industrial water hardness measurement.
In the own chemical laboratory of Gebrüder Heyl Analysentechnik GmbH & Co. KG the suitable indicators and reagents for the devices are produced.
We develop and manufacture individual analytical instruments for industrial and commercial water treatment plants on behalf of our customers.
A large number of our partners and customers regularly make use of the NEOMERIS product range for their product and plant solutions, up to individually designed products and plant systems that meet today’s high quality standards.
From UV systems to ozone generators, dosing controls, pH measuring systems, conductivity transmitters and also probe measuring systems for e.g. turbidity, chlorine, ammonium or multi-parameter solutions as well as rapid testers for water treatment and gas measuring systems, e.g. for H2O2 can be supplied from “one source”.
