Evaluation of Conductivity Meters for Firefighting Foams

Five conductivity meters were evaluated against the standard refractometer. There were some variations to the operation and calibration of the conductivity meters that made some meters slightly better than others. It was determined, however, that all five conductivity meters were more accurate and easier to use for conducting tests on foam-proportioning systems than the refractometer.
