Built with a PPS plastic body and NPT process threading, this pH and temperature transmitter outputs both 4-20 mA and RS485 Modbus signals. Moreover, it references 0 mV to 4.6 pH and includes a 19' (5.8 m) cable. Supplied without an electrode, it suits water treatment, process control, and wastewater pH monitoring.

MJK pHix Compact is an innovative pH meter and redox transmitter that can be immersed in liquids in channels and tanks for accurate measurements. When measuring in pipes, it is possible to mount the pHix Compact in a 2"pipe socket. pHix Compact is IP68 secured and can therefore withstand up to 1 bar/10 mWG pressure and full immersion.
This version features analog 4-20 mA or Modbus RS 485 signal output. Furthermore, firmware upgrades are now possible due to the RS 485 Modbus communication protocol. The new design in PPS Fortron makes the pHix® Compact v.3 almost 100% corrosion resistant. In addition to measurements in wastewater, due to the new rough materials and long-term stability of the sensor and electrode, the pHix® Compact v.3 is now very suitable for pH measurement in waste & drinking water, marine, process, industry and aquaculture. The advanced and unique design of pHix® Compact v.3 ensures that your work is done fast, easy and with high accuracy.
The compact design offers a union in one end, and male thread in the other. This makes it easy to mount pHix® Compact v.3 in pipelines or immersed in open tanks. MJK offers a wide range of fitting and mounting accessories. The double-junction electrode is developed especially for pHix® Compact v.3 and will provide significantly higher impedance, increased electrolyte volume, increased junction area and a longer lifetime compared to most traditional electrodes. New pHix Link application tool for setup, calibration, electrode diagnosis and troubleshooting is connected easily using a standard Windows laptop over the build-in serial communication.
