[ Convenience Use ] 5 Seconds know water quality, Accuracy, Faster. This set Combo of TDS PH EC Temperature. Also it have Best Price, Trustable Quality, all make it be your FIRST water quality Test.
[ Lasted el ] PH pen have AUTO CALIBRATION function, not need any kind of screwdrivers to calibrate the pH pen tester.TDS pen have Lock & auto shut off function. [ Pocket Portable ] Small size but Suitable for testing pH balance of drinking water, pool, aquarium, RO system, Spa, or hydroponics.
Application: pure water production and drinking, tap water, well water, sea water,fish tank water, swimming pool water, amniotic fluid early break, soil, aquaculture, food processing, saliva, enzyme, chemical experiment, ionized water, PH value of human urine and so on.
How to Measure: Prepare:Remove the protective cap from the handheld meter.Keep Reading Stabilize. Press the ON/OFF button to turn on the unit. Dip the electrode in the target solution, making sure the whole electrode is submerged. Stir the solution gently and wait for the value to stabilize. The LCD screen will display the reading.How to Store:;Rinse the electrode with distilled water and let it dry.
TDS Meter: Lock function - makes it easy to read and record, press HOLD button then remove from test solution. 4 Display es: press SHIFT button: TDS - ppm & Celsius, EC - μs/cm & Celsius, TDS - ppm & Fahrenheit , EC - μs/cm & Fahrenheit . 5 minute Auto Shut Off feature, so battery won't run down.

Calibration of the pH meter
1, the calibration powder with 250ml of distilled water or pure water to open. Dip the pH electrode into a mixed phosphate standard buffer at pH 6.86 and shake gently.
2, push the CAL button,it will auto calibration until the displayed value and the standard buffer solution at pH 6.9 consistent with the ambient temperature.
3, the same as above, the electrode was inserted into pH4.01 Phosphorous stupid acid potassium bicarbonate standard buffer solution.
4, about two minutes or so. The displayed value should be within the error tolerance compared to the pH value of the buffer solution.
