Water is our Element

Gebrüder Heyl Analysentechnik GmbH & Co.KG has been working in industrial water treatment for over 60 years.
We develop and produce measuring and control equipment for the water analysis with 50 employees. Our Testomat series measures more than 20 parameters, including hardness, carbonate hardness, free chlorine and chlorine dioxide.
Our devices are used, for example, in the production of drinking water, in swimming pools, in the food industry as well as in industrial cooling and heating circuits.
Our Chemical Division produces the appropriate indicators and reagents for the devices. In addition we develop and manufacture individual analysis instruments on behalf of our customers.
