PCE Instruments – Conductivity Meter PCE-PWT 10

The conductivity meter is a compact device with an integrated temperature sensor for optimum temperature compensation. It is a good solution for anyone who wants to check the conductivity of ultrapure water. Among other things, the conductivity meter has a very low measuring range of only 0 … 20 μS / cm.

Furthermore, the conductivity meter is able to accurately determine the salinity of liquids. It has an automatic temperature compensation in the range of 0 … 60 ° C. The calibration of the conductivity meter is carried out via a three-point calibration.

For the desalting stage of water purification, the conductivity meter is helpful. Separation of salt is a necessary process and can be monitored by the conductivity meter. The latter are a part of both electrodialysis and reverse osmosis. Though the purpose is the same, the principle of these processes is different. Reverse osmosis is a successor of electrodialysis and if the latter uses electrical current, the former is based on pressure. For desalting of water, forward osmosis may also be applied, which helps to separate the dissolved solutes from the pure water. Both methods are aimed at improving the pure water quality. This quality can be checked in the end by the conductivity meter.

Conductivity is a material-specific ability to conduct electrical current. The electrolytic conductivity of aqueous solutions depends on the concentration of water constituents, their degree of dissociation, and the valency of the cations and anions, as well as the mobility of these ions, which in turn is influenced by the temperature. Our conductivity meter can accurately determine the ion content. In wastewater, conductivity is considered as a sum parameter for the ion concentration and thus for the total salinity. With the help of our conductivity meter, it is possible to make a quick and easy statement about the total content of dissolved salts in the water.
