pH Analyzer MPH 66
The analyzer can measure pH in a one or two channel system. The sensors can be installed at one point or at different points up to 1000-m distance from the analyzer. The analyzer can produce an arithmetical average of both measurements. The arithmetical average can be used as an input value for the controller. Measurement can be completed with two temperature measurements. The pH value can be automatically corrected by temperature.
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 semi-continuous movement. The analyzer can be also supplied with closed loop control 0(4) - 20 mA.
The semiautomatic calibration with the automatic buffer identification and system check makes, calibration easier and prevents human error.
The analyzer is supplied in version T for indoor installation and in version V for outdoor installation.
