【Easy to Use】When testing liquids, you just need to look at the numbers on the meter’s digital display, and you can know the TDS PH EC water temperature reading by 5 seconds, not comparing with the test paper, which is more efficient and faster. TDS and EC testers measure total dissolved solids (TDS), electrical conductivity (EC) and temperature. 【Automatic humanized design】Automatic temperature compensation automatically takes into account temperature changes (0~80 degrees). The pH meter does not need to adjust the screwdriver, just use the auto calibration button to complete the calibration, and comes with a buffer powder. [High Accuracy] The digital range of the PH meter is 0.00-14.00 (PH), while the digital range of EC and TDS digital meters is 0-9990ppm. pH resolution 0.01pH, Accuracy ±0.05pH.TDS: 0~9990ppm, Conductivity: 0~9990us/cm, Accuracy: ±2%. [Extensive Applications] Water Quality Tester water ideal for drinking water, aquariums, fishing, swimming pools, RO systems, spas
