Conductivity / resistivity sensors for monitoring pure water conductivity are available in 2-electrode and 4-electrode models to cover all ranges of measurement. UniCond models have built-in measuring circuits and analog to digital signal conversion in the sensor head, which enables performance far exceeding that of conventional sensors. This helps you to achieve the highest accuracy in pure water conductivity monitoring applications.

The Highest Accuracy and Widest Measuring Range

Ensure Compliance of Pharmaceutical Waters
Monitoring water conductivity in pharmaceutical waters must be done within pharmacopeia guidelines. UniCond conductivity sensors from METTLER TOLEDO Thornton fulfill USP <645> and other global pharmacopeia requirements for cell constant accuracy, resistance measurement circuit, resolution, accuracy and temperature compensation.

Maximize Yield in Semiconductor Manufacturing
Continuous readings from accurate resistivity sensors are critical for monitoring ultrapure water (UPW) in semiconductor and electronics manufacturing. UniCond conductivity / resistivity sensors are trusted by semi fabs the world over to help them maintain their UPW system and prevent water system problems that can have a negative effect on wafer quality and production yield.

Prevent Corrosion in Power Plants and Boilers
Water conductivity measurements are important in power steam quality monitoring to prevent corrosion of turbines and boilers. UniCond digital and analog pure water conductivity sensors allow for measurement of conductivity, even in high temperature waters and steam applications. The degassed cation conductivity panel, the DCC1000e, provides more sophisticated monitoring for faster power plant start-up and turbine compliance.
