【Easy to Use】When testing liquids, you only need to look at the numbers on the meter’s digital display, and you can get the TDS PH EC water temperature value in 5 seconds without comparing it with the test paper, 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 accounts for temperature changes (0~80 degrees). The PH meter does not need to be adjusted with the screwdriver, just use the automatic calibration button to complete the calibration, and comes with a buffer powder. [High Precision] The digital range of the PH meter is 0.00 to 14.00 (PH), while the digital range of digital EC and TDS meters is 0 to 9990 ppm. pH Resolution 0.01pH, Accuracy ±0.05pH.TDS: 0-9990ppm, Conductivity: 0-9990us/cm, Accuracy: ±2%. [Wide Applications] Water Quality Tester, ideal for drinking water, aquariums, fish tanks, swimming pools, RO systems,
