The ORPMA is a two-wire, 4-20 mA blind transmitter which provides a low cost solution for converting the signal of an ORP electrode into a 4-20mA output. It is ideal for direct input into PLC or other devices. A loop powered display can be used for local display if required. Multi-turn pots allow adjustment of zero and span.
The Signet 8750 pH/ORP Transmitter is designed for broad application and ease of setup and use. The unit auto-configures for either pH or ORP use when connected to Signet pH or ORP sensors. Multiple mounting options allow for installation best suited to your particular application.
