Thermal conductivity sensor

digital4-20 mARS-232

Our Single-Use Conductivity Sensors™ and Conductivity monitor integrate for highly accurate conductivity and temperature measurement without the need to calibrate the conductivity electrode because of its predetermined cell constant. For use in critical bioprocess operations the sensor monitor reads conductivity and temperature from up to two sensors. No calibration is required because the cell constant must be entered when new sensor is connected. There is temperature normalization to 25°C with an adjustable mS/ °C factor. The monitor has 4 – 20mA outputs for both conductivity and temperature and an RS232 output for data collection to a PC.
