Krypton K Multi
Online measuring and control system for free Chlorine, pH-value and Temperature - optionally with ORP measurement
- Low maintenance by automatic sensor cleaning ASR
- Particulary suitable at unsteady pH-values through pH compensation
- Higher safety by integrated flow monitoring
description
Ready to use and tested en bloc measuring system for automatic measuring and controlling of free Chlorine, pH-value, and temperature. An ORP measurement can be added - as an option. Chlorine concentration and pH-value can be controlled by separate PI-controllers.
components
Scope of supply is: measuring and control instrument K 400, free Chlorine sensor, pH sensor, flow assembly GDM with Pt100 (with sampling point, stop cocks for in- and outlet, measuring water filter, flow monitoring and temperature sensor), automatic sensor cleaning ASR for free Chlorine and all necessary cables.
applications
Disinfection
Drinking Water / Beverages
Cooling And Boiler Feed Water
