The PHTX-100 pH/mV transmitter is a loop-powered 4 to 20 mA transmitter with a wide range of useful features and programmable options. Five buffer choices are available in two-point calibration mode. The 4 to 20 mA output is saleable in pH or mV units and has 500V input to output isolation.

Temperature is always displayed and is selectable in °C or °F. All stored parameters and calibration data are retained in the non-volatile memory during transmitter power down or power loss. A useful probe clean reminder icon flashes when it is time to clean the probe. Probe cleaning interval is user programmable from 1 to 250 days.

The PHTX-100 can be used for wall mounting, panel mounting, pipe mounting and DIN-rail mounting. Cable glands for inlet/outlet to box are included as well as all mounting hardware. The case meets IP65 (NEMA 4X) ratings for ingress protection.
