German Innovation,

Distributed Worldwide.

Heyl Brothers 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 measure over 20 parameters including water hardness, carbonate hardness, free chlorine, and chlorine dioxide. Our analyzers are used globally to monitor water quality.

You can find our analyzers:​

  • in waterworks in monitoring the quality of drinking water

  • in the production of food and cosmetics

  • in power plants for heat and power generation

  • in hospitals in the sterilization process of surgical instruments

  • for the monitoring of process water needed for the production of glasses or DVDs

  • in the pharmaceutical industry for the production of high-quality medicines

  • in developing countries in the monitoring of well water

 

In addition to the development and production of devices, we have our own chemical department to develop and manufacture indicators and reagents used in our analyzers.

Our Services

Contract Development

We develop innovative, customized designs ourselves.
We provide an appropriate housing design, prepare technical documentation, and obtain the necessary sales permissions and certificates. We also handle series production.

We implement your idea. We manufacture your product!

Heyl Brothers sets a high value on the reliability and durability of our products and have adapted the supply of spare parts to the long service lives of our instruments.

100% Testing

In addition, great value is attached to multi-level 100% testing, only possible on the basis of small-batch production.

All assemblies are tested separately before they are installed in our instruments and then subjected to a multi-day quality check in the instrument.
