[Easy to use] Just see the number on the digital display of the meter when you test the liquid, 5 seconds know the TDS PH EC water temperature reading, no need to compare with the test strips, this which makes it more efficient and faster. TDS and EC tester measures total dissolved solids (TDS), electrical conductivity (EC) and temperature. [Automatic humanized design] Automatic temperature compensation automatically takes into account temperature changes (0 ~ 80 degrees ). PH meter No adjustment screwdriver needed, just complete the calibration with the auto calibration button and included buffer powders. [High precision] The numbers of the pH meter range from 0.00 to 14, 00 (PH), while the numbers of the EC and TDS digital meters range from 0 to 9990 ppm. The resolution of pH is 0.01pH, accuracy ± 0.05pH.TDS: 0 ~ 9990ppm, conductivity: 0 ~ 9990us / cm, accuracy: ± 2%. [Portable and upgrade] Con ? u according to the convenient size which is ideal for carrying in your pocket and
