AquaMetrix PTX and RTX Smart Differential pH and ORP Sensors

The TX sensor's improved, universal flat-faced glass process electrode is designed for tough applications. A larger surface area guarantees quick readings and outstanding performance, and a self-cleaning flush fit when installed inline dramatically reduces upkeep time and effort.

The process electrode is encased in a protective layer of PPS offering increased resistance to physical damage. Differential measurement technology uses two glass electrodes to make the measurement differentially with respect to a third metal electrode. The resulting true differential measurement virtually eliminates ground loop problems,  and the sensor can be restored to factory condition at modest cost by replacing the salt bridge and reference solution.

Automatic temperature compensation is improved through the use of a thermistor at the tip of the probe, providing rapid response for process temperature variations.

The digital output sensors provide reduced noise, higher immunity from stray voltages, calibration stored in the sensor, and the elimination of intermediary transmitters. If you need or want local control, datalogging, or display, the TX sensors are compatible with the AquaMetrix AM-2300 multiple-input controller.

The replaceable salt bridge, which prolongs the life of your sensor, has been redesigned so you don't need special tools to remove or install it. Just grab a #3 Philips screwdriver or 1/2" wrench and rejuvenate your sensor in seconds.
