Company Portrait



Gebrüder Heyl Analysentechnik GmbH & Co.KG
has been working in industrial water treatment for over 60 years.

We develop and produce measuring and control devices for water analysis. With our Testomat series you can currently measure over 20 parameters such as water hardness, carbonate hardness, free chlorine and chlorine dioxide.

Our devices can, for example, be found in drinking water production, in the swimming pool industry, in food production, as well as in industrial cooling and heating circuits.

In addition to the development and production of devices, we have our own chemical department which works in the development and manufacturing of the indicators and reagents that work with our devices.
