• Product Image- 8860 Controller

    The +GF+ SIGNET 8860 Dual Channel Conductivity/Resistivity Controller is a two-channel input device equipped with three scalable 4 to 20mA outputs and four programmable relays. A selector switch activates two open collector outputs in place of two of the relays for extraordinary output versatility. The four-button keypad arrangement with intuitive software design is user-friendly, and the NEMA 4X/IP65 integrity of the front panel can be extended to the enclosure by using the optional Rear Cover kit.

    Discontinued - No Longer Available        (See 9900 Transmitter)

    The +GF+ SIGNET 8850 Conductivity/ Resistivity Transmitter is designed for broad application and ease of setup and use. The unit can be used for conductance, resistance, or TDS signal transmission and display. Mounting can be accomplished in several options best tailored to your application requirements. Full-microprocessor based electronics allow wide operating range, and long term signal stability due to the elimination of potentiometers, jumpers and dip switches.
