ORP Transmitter

The ORP Transmitter is our most cost-effective solution for connecting our S8000 series ORP sensors to the Opticlear, PLC, or SCADA systems. This small electronic module functions as a blind ORP transmitter with a 4-20mA or MODBUS/RS485 output. No additional instrumentation is required to condition the sensor signal to be read by your system. It can also be used to pair sensors with any controller that has a 4-20mA or RS485 input card.
