ORP Analyzer MRP 66
This analyzer can measure ORP simultaneously from two sensors or it can measure ORP and pH. Two temperature measurements can be added. Sensors can be installed at one point or at different points up to 1,000-m distance from analyzer.
The analyzer can produce an arithmetical average of both measurements. The arithmetical average is converted to current signal to the third output and can be used as an input value of controller.
The analyzer contains one or two PID Controllers with width or frequency pulse output. Output can be unidirectional for solenoid valves or dosing pump control, and bi-directional for control drives with continuous movement. The analyzer can be also supplied with closed loop control 0(4) - 20 mA.
The analyzer is supplied in version T for indoor installation and in version V for outdoor installation.
