Measuring Conductivity of Water with Varying Purity Levels & Temperatures with UniCond Sensors

This video provides an overview on what conductivity and resistivity are, and their role in monitoring the purity levels of different types of water. It discusses the relationship between conductivity measurements and the purity level of water, and then goes into some of the common challenges of measuring the conductivity of water in process and pure water applications. Those challenges are often tied to having to use and manage multiple models of conductivity sensors to accommodate the wide measuring range in a typical water treatment system, and compensating for changes in temperature.
The video also introduces UniCond® wide-range, digital conductivity sensors as a way of eliminating those problems and simplifying the selection of your conductivity sensors.

What is conductivity? It is the measure of a material's ability to carry an electric charge. Conductivity and its reciprocal measurement, resistivity, are important analytical parameters for measuring the purity of different types of waters, including process water and pure water. As water is purified, it's conductivity is typically reduced by at least four orders of magnitude.
With a wide conductivity measuring range to cover on a typical water system, you typically need different conductivity cell constants that are optimized for each stage of treatment. This means a variety of different sensors.

METTLER TOLEDO UniCond digital sensors allow you to measure a much wider range than conventional analog sensors. This means you if you use UniCond digital sensors, you don't necessarily need different conductivity sensors for different parts of the process where concentrations differ substantially. Using one sensor for your whole range reduces costs by making specification, installation, start-up and documentation simpler.
Another challenge in conductivity measurement is temperature compensation. Conductivity measurements can vary up to 5% per degree of temperature change, meaning the same concentration can have very different conductivity readings at high and low temperatures. Digital sensors compensate for this difference, giving you the right reading regardless of the temperature.
