Premium TDS Meter Digital Tester The TDS meter Highly efficient and accurate due to its advanced microprocessor technology, +/- 2% Readout Accuracy Testing, the titanium alloy probe has high test accuracy, reliable Automatic Temperature Compensation (ATC),which can avoid the interference of magnetic field in water. 2Testing range from 0-9990 ppm, ppm. The TDS meter reading will be displayed on the LED screen in ppm (parts per million), one million). One measurement can be completed within 5 seconds. Product Specifications Product Name:PH meter Range:0.0-14.0PH Resolution:0.01PH Temperature compensation:0℃ -50℃ Operating Temperature:0℃ -60℃ Accuracy:±0.01PH Easy to Use Remove the protective cap. Turn the Tds meter on. lmmerse the meter into the water solution up to the maximum immersion level(5 cm) Wait until the display stabilizes, The TdS meter automatically compensates for temperature variations. Once the readout is stabilized (30 fo 45 seconds and then press the hold button to save readings. After usage shake off water from your meter or wipe it with tissue.
