Indicator 320 for increased residual hardness values in the Testomat 808
Reliable analysis solution for residual hardness up to 2 °dH
In combination with the indicator solution and the Testomats, it supports the continuous monitoring of water quality parameters. This indicator is particularly suitable where higher residual hardness ranges are relevant and stable, reliable limit value displays are required. Its liquid form allows for easy application directly in the measuring device.
