Produktbeschreibung

general information:

The conductivity converter UNICON®-LF has been designed for the measurement of the condutivity in liquids. Depending on the conductivity of the medium, 2-electrode measuring cells (e.g. ultrapure water) or 4-electrode measuring cells (e.g. process water, detergent solutions, acids, alkalis, etc.) are required.
