Description
The ST-720 is a uniquely designed industrial grade inline conductivity sensor that offers greatly improved range, accuracy and stability with anti-interference capabilities. A built-in transmitter supports both digital and analog signal output, designed to simplify on-site installation, calibration and operation. The ST-720 contains a 4-Graphite Electrode Configuration with a scale of 1–100,000µS/cm, allowing the sensor to be less prone to fouling and deposition. This sensor maintains conductivity accuracy and precision – without the need of frequent calibrations – within a 1.5% µS/cm.
Furthermore, the ST-720 contains an embedded PT-100 RTD temperature sensor allowing for automatic temperature compensation. The unique flat surface makes sensor cleaning and calibration extremely easy. The sensor is provided with the ST-001 inline tee (3/4inch FNPT Format). Therefore, the ST-720 may also be installed with the MA-102S Submersion Adapter. Furthermore, the ST-720 offers two 4–20mA output signals (temperature and conductivity) with integrated transmitter as well as RS-485 Modbus digital output. Finally, as with all Pyxis Lab® sensor, the ST-720 can be diagnosed, cleaned and calibrated in wireless format when used with the MA-WB or PowerPACK series and the uPyxis® app.
