Expansion of conductivity sensor portfolio with UniCond® 4-E digital sensors.

Mettler Toledo Thornton has announced the expansion of its conductivity sensor portfolio with the UniCond® 4-E digital sensors.

The new four-electrode sensors have been designed to provide highly accurate measurement across a very wide range: a single UniCond 4-E measures from pure potable water to acid or base concentrations.

Applications for the UniCond 4-E series include Clean-in-Place and desalination processes, deionization regeneration, industrial processing, and wastewater treatment.

Analog conductivity sensors are prone to signal degradation caused by sensor-to-transmitter cable resistance and capacitance.

Mettler Toledo Thornton has solved this issue by incorporating technology into the UniCond sensors that converts the analog signal into a robust and reliable digital signal.

In addition, the sensors contain Mettler Toledo's Intelligent Sensor Management (ISM®) concept. Features of ISM include Plug and Measure start up at the measurement point and sensor diagnostics for proactive maintenance.

In addition, the UniCond 4-E can be calibrated without extraction from the process. This makes the sensors compliant with United States Pharmacopeia (USP) guidelines.

"Mettler Toledo’s new conductivity sensors offer substantial improvements in accuracy, rangeability, and stability compared with analog sensors,” says Christie Martin, Conductivity Product Manager at Mettler Toledo Thornton. “Combined with the benefits of ISM, the UniCond 4-E sensors provide exceptional performance in a wide range of chemical, pharmaceutical, and power industry applications."
