For more than 60 years Heyl has been supplying online measuring instruments for the determination of water hardness parameters as well as non-hardness parameters. 

All Testomat instruments work on the basis of photometric measurement. The Heyl Testomat world of instruments offers you a comprehensive product portfolio ranging from limit value determination for hardness using Testomat 808 or for silicates using Testomat 808 SIO2 to full-scale measurement parameter determination, e.g. with the new instrument variants Testomat EVO and Testomat LAB. 

The entire world of Heyl Testomat instruments can be integrated into our NeoTecMaster multiparameter system, so that all measurement data can be read from any location.
