Process Analytics Division introduces Thornton UniCond conductivity sensors with in-line calibration capability.
The enhanced sensor electronics allow calibration using a patent pending UniCond calibrator without removing the sensor from the process. The in-line calibration capability is an important factor in pharmaceutical water compliance, microelectronics fabrication, power generation as well as pure water and steam applications.
Designed to meet USP ‹645› and EP requirements, the new UniCond calibrator provides NIST-traceable resistances for all ranges of the UniCond measuring circuit.
The ultra-wide conductivity measurement range from ultrapure water to seawater with one sensor is a major advantage of the UniCond conductivity sensors. The stainless steel sanitary sensors offer a measurement range from 0.02 to 2,000 μS/cm with ±1% system accuracy to meet pharmaceutical water requirements.
The UniCond sensors may be used with Thornton M300 ISM or M800 multi-parameter 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.
According to product manager Christie Martin, the UniCond conductivity sensor provides a unique solution for in-place electronics calibration to meet USP ‹645› and EP Pharmacopeia requirements. The new UniCond calibrator simultaneously connects the UniCond conductivity sensor and Thornton ISM transmitter to calibrate the system electronics while remaining connected to the water system.
