Model 100-ORP

Dual Limits & Dual Alarms ORPController with Iso 4-20mA Tx Output

Features

Model 100 ORP controller is panel mounted DIN size instrument with 3½ Digit LCD.
Indicates the value of Oxidation-Reduction Potential (REDOX) when attached to an ORP electrode.
The membrane key Mode Switch in front allows indication of normal ORP millivolt, Limits for Oxidation/Reduction, together with additional Alarm Limits for Oxidation/Reduction.
A consent contact input, at the rear, enables all control outputs. This consent input is the output of a pH controller. The equipment also provides an isolated 4 to 20mA output for recorder purpose.
