For the continuous monitoring of the residual hardness in soft water

As protection against hardness break-throughs downstream of ion exchanger systems. Short-term, minor hardness break-throughs (e. g. when the entire system is started) do not cause any alarms. Hardness meter with stop valves and hose connections, control unit with visual operating and hardness indication and output for visual/acoustical signal and/or shut-down function of a system downstream. Differential pressure transducer, measuring hose with connections, spare sensor.
