PH Meter,TDS PPM Meter,PH/EC Digital Kit,Pool Water Test Kit,0.01 Resolution TDS PH EC Temperature Set for Home Water,Drinking Water, Hydroponics, RO system, Aquarium, Swimming

Parts List:

1× PH Meter Digital Water PH Test Pen

1× 3-in-1 TDS EC and Thermometer

PH Meter TDS Meter Combo, Pool Water Test Kit, PH Tester Digital, PPM Meter

PH & TDS meters all are accurate, reliable and easy to use

Digital pH meter works for testing water's pH, 3-in-1 TDS meter works for testing water's EC, TDS and temperature

They are used for testing liquid's quality, such as drinking water, hydroponics, aquaculture, RO system, aquariums, swimming pools, SPA and so on

Please kindly note as below:

PH meter's accuracy was improved, and it will take longer in testing.

In calibrating, pressing CAL button after pH meter reads calibration solution stably.

3-in-1 TDS meter was calibrated by 1413 solution in producing, does not need to recalibrate.

3-in-1 TDS meter's probe is titanium alloy, doesn't suit for testing sea water。

PH TDS Meter

Calibration of the pH meter

1.   The calibration powder with 250ml of distilled water or pure water (Do not use tap water and mineral 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

Directions

PH Meter: 1.   Use the PH meter to test water's pH. 2.   For calibration, press the CAL button after the PH meter reads the calibration solution stably.   3-in-1 TDS Meter: 1.   Use the TDS meter to test water's EC, TDS, and temperature.   2.   The probe is titanium alloy, which does not suit for testing sea water.   3.   The TDS meter was calibrated by 1413 solution in producing, does not need to recalibrate.   4.   The meter has lock & auto shut off function, just need to push the button, and it can display the data about water purity level on the screen in PPM (parts per million).
