Mettler Toledo Thornton UniCond conductivity sensor

Mettler Toledo Process Analytics Division has introduced the Thornton UniCond conductivity sensor with inline calibration capability. Enhanced sensor electronics allow calibration using an accessory UniCond calibrator without removing the sensor from the process. This is a critical factor in pharmaceutical water compliance, microelectronics fabrication, power generation, pure water and steam applications.

The UniCond calibrator is a digital conductivity system that meets USP <645> and EP requirements. It provides NIST-traceable resistances for all ranges of UniCond measuring circuit. A major advantage of the sensor is its ultra-wide conductivity measurement range, from ultrapure water to seawater with one sensor. Stainless steel sanitary sensors have measurement ranges from 0.02 to 2000 μS/cm total range with ±1% system accuracy to meet pharmaceutical water requirements.

The sensor may be used with Thornton M300ISM or M800 multiparameter transmitters, which enable the use of two or four digital sensor inputs for continuous measurement of ozone, dissolved oxygen, conductivity, pH and total organic carbon.
