The Model Rosemount Analytical Model 141 sensor is an insertion type contacting conductivity sensor having a 3/4 inch MNPT process connector.

The sensor is available in both a low temperature (302°F (150°C)) and high temperature (392°F (200°C)) version. Both versions use 316 stainless steel electrodes with a PEEK insulator and Viton® O-rings. Wiring between the sensor and analyzer is through a junction box mounted on the back of the sensor.

Cell constants of 0.2/cm and 1.0/cm allow the sensor to measure a broad range of liquids having medium to high conductivity.
