Water Test Multimeter

All in one pocket sized waterproof test meter for pH, conductivity, TDS, salinity and temperature! Tester stands up to everyday use, harsh environments, and the test of time. The tester can even stand upright when the cap is used as the stabilizing base. Great for water, wastewater, laboratory or plant use, the tester features long-life pH electrodes with a wide range of sample compatibility. Pin-style conductivity sensors feature stainless steel electrodes for chemical resistance and durability. Replaceable sensor module saves you money by reusing the meter body.


The PCTSTestr50 combines 5 measurements in one pocket-sized meter. The large upright display is easy to read. The IP67-rated waterproof, dustproof housing protects your instrument from rugged field or plant environments. A large volume of polymer gel reference gives long, clog-free, sensor lifespan. The waterproof battery compartment is easy to use; simply unscrew cover to replace batteries; no tools required. The automatic temperature compensation function gives you accurate readings even with fluctuating temperatures. Additional features include push-button calibration, hold function and auto shut-off function. The PCTSTestr50 is ideal for water quality applications such as hydroponics/agriculture, research labs and industrial process checks.
Test Modes: pH, Conductivity, TDS, Salinity and Temperature.
