Supported Applications
The Omega PHTX-100 is a loop-powered, microprocessor-based pH/mV transmitter designed for industrial process monitoring applications. It functions as an indicating meter and transmitter capable of measuring both pH levels and oxidation-reduction potential (ORP) in millivolts.
Operating Conditions & Performance
The PHTX-100 operates within a process temperature range of -20 to 120 °C, with an ambient operating temperature limit of -20 to 60 °C. Storage is supported from -40 to 85 °C in environments up to 95% RH (non-condensing). The unit features a polycarbonate housing rated NEMA 4X / IP65 and withstands pressures up to 100 psi (6.9 bar).
Performance specifications include:
- pH Measurement Range: 0 to 14 pH
- mV Measurement Range: -1999 to 1999 mV
- Accuracy: ±0.01 pH and ±1 mV
- Resolution: 0.01 pH / 1 mV
- Response Time: Less than 1 second
Configuration Options
The series supports a digital display and keypad for setup and calibration, providing local indication alongside remote transmission. The transmitter is powered by a 4-20 mA loop with an external power supply requirement of 10 to 30 VDC.
Output Signals & Electrical
- Analog Outputs: Configurable for 4-20 mA or 0-10 V signals
- Load Resistance: Maximum 500 Ω
- Electrical Connection: TBMI1 terminal block (as shown in Figure 5-1)
Housing & Physical Dimensions
- Dimensions: 100 mm x 100 mm x 50 mm
- Weight: Approx. 0.5 kg
- Material: Polycarbonate enclosure
Key Product Differences
The PHTX-100 is a single-model series identified by the part number PHTX-100. It is manufactured in the USA and carries CE marking along with ISO 9001 certification (Stamford, CT and Manchester, UK). The device does not support user repair or replacement parts from other suppliers per manufacturer warnings.

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.

What is the current draw of PHTX-100 (i.e. for circuit breaker sizing)?
Thank you for your inqury about the pH transmitter. Using Ohm's Law to calucate the current draw an email had been sent since it contains a chart with different loads and voltages.

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.
