Description
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 ºC or ºF. 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 grips for inlet/outlet to box are included as well as all mounting hardware. The case meets NEMA 4X (IP65) ratings for water resistance.
