FAQs

What is a pure water conductivity sensor?

A pure water conductivity sensor (or water conductivity cell) measures the ability of a solution to conduct an electrical current in pure water systems. It is the presence of ions in a solution that allows the solution to be conductive: the greater the concentration of ions, the greater the conductivity. These in-line pure water conductivity sensors are specially designed to measure accurately in low conductivity waters. In microelectronics and semiconductor production, the purity measurement of ultrapure water (UPW) is made as resistivity (the reciprocal of conductivity). 

How many types of pure water conductivity sensors are there?

METTLER TOLEDO's flagship pure water conductivity sensor is the UniCond. This is a family of digital conductivity sensors especially designed for pure water monitoring. 

Within the UniCond family there are two technology types of measurement technology that pure water conductivity sensors use:

  • 2-electrode pure water conductivity sensors
  • 4-electrode pure water conductivity sensors

How do you calibrate a pure water conductivity sensor?

A METTLER TOLEDO water conductivity sensor can be calibrated against a solution of known conductivity (much like calibrating a pH sensor against a solution of a known pH). Alternatively, an in-line water conductivity sensor that contains a range of very precise resistors that duplicate known pure water conductivity measurements can be used. 

For applications in the pharmaceutical industry, special considerations should be made for compliance purposes when calibrating a pure water conductivity sensor. The UniCond Calibrator and Pharma Waters Verifier can help ensure that your calibration is pharmacopeia compliant.

What transmitters are METTLER TOLEDO pure water conductivity sensors compatible with?

Pure water conductivity sensors can integrate with any appropriate METTLER TOLEDO water transmitter that is suitable for conductivity.  These conductivity transmitters include the M300 Water and M800 Water transmitters. The exact transmitter for your application should be selected in consultation with your local METTLER TOLEDO representative.
