The Ultrameter II 6PFCE water quality tester allows you to measure Conductivity, Resistivity, TDS, ORP, Free Chlorine Equivalent (FC^E) concentration, pH, and Temperature all with the press of a button. Get empirical measurements of the chemical activity of a solution without the hassle and subjectivity of colorimetric and test-strip methods. The groundbreaking FC^E measurement is the fast accurate way to determine the killing power of free chlorine species in water. It employs a proprietary predictive ORP algorithm to determine free available chlorine levels at the actual pH of water, so you know your chlorine treatment is effective. Following colorimetric measurement requirements may increase chlorine usage unnecessarily or give a false impression of clean and safe water.
