Automatic temperature compensation. Simple wiring with removable terminal modules. The mV 600 controllers have been engineered with the same outstanding features as the pH 500 meters. The fail safe alarm system protects these meters against the pitfalls of process control. User selectable timing capability safeguards against overdosing. These instruments have a differential input, extending electrode life by eliminating ground loop current through the reference. Users can choose between ON/ OFF and proportional control as well as selectable current and voltage output. For more flexibility and better resolution for chart recorders, choose any two points between 0 and 2000 mV to correspond to the analog output spans. RS232 capability makes two mV 600 models PC compatible. Wiring the controllers is simple with extractable terminal modules. A host of self-testing features and user friendly functions make mV 600 a great value. single setpoint, on/ off control, analog output, 115V. Range: 1 mV ORP, -9.9 to 120 degree celsius temperature.
