500 ml residual hardness indicator 300 S for Testomat 808
Liquid solution for precise detection of residual hardness in water
The Testomat 808 indicator 300 S was designed by Heyl for applications in which defined residual hardness thresholds must be reliably monitored. With a fixed limit value of 0.05 °dH, this indicator is intended for technical water systems in which controlled, consistent water quality is crucial. The 500 ml bottle supports continuous use in automated measurement processes and reduces interruptions during operation.
