METTLER TOLEDO THORNTON 240-214 CONDUCTIVITY / RESISTIVITY SENSOR 240214

Description:

The Mettler Toledo Thornton 240-214 Conductivity/Resistivity Sensor is used in high-purity water analysis systems to accurately measure conductivity and resistivity for process monitoring and quality control. Commonly installed in pharmaceutical water systems, semiconductor manufacturing facilities, power generation plants, ultrapure water systems, and industrial water treatment processes utilizing Thornton M300 and compatible analyzers. Maintenance technicians and system integrators use this sensor for process instrumentation maintenance, sensor replacement, system calibration, and restoration of accurate water quality measurements.

Applications:

The Thornton 240-214 sensor provides continuous conductivity and resistivity measurement with integral temperature compensation for high-purity water and process solutions. It is widely used in reverse osmosis systems, deionized water systems, water-for-injection (WFI) systems, clean-in-place (CIP) processes, boiler feedwater monitoring, and semiconductor rinse water applications where precise conductivity and resistivity monitoring are critical.
