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.
