Oxidation Reduction Potential meters and ORP controllers.
The industrial ORP transmitter is a 2-wire 4-20 mA ORP transmitter enclosed in a sealed NEMA-4 enclosure. The industrial ORP transmitter has an LCD screen powered by 11 to 80 VDC. The ORP transmitter's span has selectable ORP values from 100 to 1400 mV units via an internal dip switch. The industrial ORP transmitters use BNC connections for the ORP transmitter's ORP sensor.
Global Water offers the PC320 ORP Controller to use the ORP transmitter's output to control pumps or alarms. Global Water's GL500 ORP Recorder adds recording capabilities to the industrial ORP transmitters. The GL500 ORP Recorder connects to the ORPtransmitter's 4-20mA output to record data.
