6PIIFCE Conductivity, Resistivity, TDS, pH, Temperature Meter, Free Chlorine. his meter replaces the older Myron L 6PII. Both Ultrameter II models deliver exceptional accuracy of ±1% of reading (not merely full scale). This high level of accuracy is achieved through advanced four-electrode conductivity cell technology, a powerful microprocessor, proprietary circuit design and conversion algorithms for three of the most common solution types, as well as a unique pH/ORP sensor. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels never before possible in such affordable instruments.
