Features
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.

The Ph Meter is not working
It is not working, we are not getting accurate measures of the pH system so we are currently pH measuring with another system.
Date published: 2021-05-04
1) Does this come with a probe or is it just the meter? 2) What probes wiring does it connect to ( BNC connection)? 3) Can we recalibrate through the display or do we have to open the box to manually recalibrate?
1) pH probes are sold separately.
2) ADAPTOR-BNCF-SL and PHE-7351-15.
3) You have to open the back of the transmitter to connect the pH probe. You calibrate the system through the display interface.

How do I get NIST traceable calibration record with this purchase?
Thanks for connecting with Omega. The PHTX-100 does not have the option for a NIST traceable certificate. We do not have any pH transmitters with this option. We have calibration solutions that are NIST traceable though. Please contact our Tech Support or email flow@omega.com for further assistance. Thanks!

Is the temp probe contained in the Ph probe ? Is there a 4/20mA output for the Ph AND the temperature ?
Thank you for your inquiry on the PHTX-100 pH transmitter. There is no temperature probe sold separately, it is from the pH probe when purchase that will need a 2-wire Pt100 RTD for Automatic Temperature Compensation.
