The ST-720 and ST-726 are uniquely designed industrial-grade inline conductivity sensors launched by Pyxis Lab Inc. that adopt the latest sensing technology with greatly improved detection range, accuracy and stability with anti-interference capabilities designed for use in complex environments. The built-in transmitter supports both digital and analog signal output, designed to simplify on-site installation, calibration and use of operation. The ST-720 and ST-726 both contain a 4-graphite electrode configuration with a scale of 1-100,000 µS/cm and 10-300,000 uS/cm respectively, allowing it to be less prone to fouling and deposition when used in challenging applications. Both maintain conductivity accuracy and precision without the need of frequent calibrations and within a 1.5% µS/cm precision level.

ST-720 and ST-726 both contain an embedded PT-100 RTD temperature sensor allowing for auto-temperature compensation. The unique flat surface also makes sensor cleaning and calibration very easy. Each sensor is provided with the ST-001 in-line Tee in ¾" FNPT format. ST-720 and ST-726 may also be installed in submersed applications while using the Pyxis MA-102S Submersion Adapter. Both sensors offer two 4-20mA output signals (temperature and conductivity) with integrated transmitter as well as RS-485 modbus digital output. As with all Pyxis sensors, the ST-720 and ST-726 can be easily diagnosed, cleaned and calibrated in wireless format when used with the MA-WB or PowerPACK Series Bluetooth adapters and the uPyxis APP for mobile or desktop devices.
