Conductivity controller LRS 1-50

The simple LRS 1-50 conductivity switch indicates excessively high or low conductivity in the boiler, and can trigger a simple valve. As an option, controllers from the LRR 1-5x series can operate in conjunction with a simple conductivity electrode and separate temperature sensor, or a conductivity transmitter from the SPECTORcompact line. Display and operation have been kept simple and adapted to suit the NRR 2-2 proportional controller. All controllers are equipped with an actual-value output.
