Oakton PCTSTestr 50 Waterproof Pocket Tester

The ultimate pocket-sized tester! This multiparameter meter measures pH, conductivity, TDS, and salinity. Choose up to three-point pH calibration with USA or NIST auto buffer recognition. Conductivity, TDS, and salinity parameters feature auto ranging based on the concentration of your sample. The meter offers one-button calibration, and the Valox® housing resists most chemicals. A specially designed leakproof cap functions as a sample cup, hydrating cup, and a stabilizing base to keep the meter standing upright. Other features include automatic temperature compensation, auto-off, self-diagnostic error messages, and a battery life indicator. IP67 waterproof. Includes storage case, lanyard, and 4 AAA batteries.
