140, 141, 142 sensor models produced by Rosemount Analytical are designed specifically for measurement of electric conductivity values at high temperature and pressure. Possibility to choose cell constant size allows to take measurements for samples with low and average conductivity values. Sensor structure is made of 316 stainless steel and allows for installation directly into the pipeline or into the tank through the wall. Sensors are design for application in pure and ultra-pure water (ideal for application at conductivity levels below 2000 µS/cm).
