PTCond 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 digital signal communication using Modbus RTU RS485 protocol, designed to simplify on-site installation, calibration and operation. PTCond contains four electrodes 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.
