Specification :

Description
1/ 4 DIN panel mount ORP controller/ transmitter, microprocessor based, password protected with membrane keypad. LCD displays ORP or pH and temp. Meter has dual SPDT Hi/ Lo relays, with programmable hysteresis and a reversible, isolated and programmable 4-20 mA output. Connectors are dual BNC for pH/ ORP and spade lug type. ATC is 10K thermistor or simulation resistor. Power 115 / 230V AC.
