DESCRIPTION:
The PeakTech P 5307 4-in-1 PH-Meter is a compact, handheld liquid quality tester designed for simultaneous measurement of the pH value, electrical conductivity (EC), total dissolved solids (TDS) and liquid temperature. Its easy-to-operate one-hand design features a backlit dual-line LCD that displays both measured values at once, even in low-light conditions. Two electrodes in the replaceable sensor head precisely capture EC and TDS, while the robust, waterproof housing ensures reliable performance in field and lab environments. Calibration controls are conveniently placed, and automatic shut-off helps preserve battery life.
