ORP Transmitters

The ORPMA is a true 2-wire 4-20 mA transmitter which provides a low cost solution for converting the signal from an ORP electrode into a 4-20mA output. Ideal for direct input into PLC and other 4-20mA input devices.   The transmitter is blind and requires a DVM to calibrate.  A loop powered display can be used for local display if required. Multi turn pots allow adjustment of zero and span. 

The best choice is our new TX100 2-wire pH/ORP transmitter. It features a local display for real time measurements and aids in calibration. Packed with powerful features, this unit features an array of user selectable options as well as input to output isolation and a multitude of mounting options, all for a fabulous price slightly more than the ORPMA. Units require 12-36VDC power. To learn more, Download specs:
