PH & TDS Meter combo
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
Package including
1 x PH Meter
1 x TDS EC Temperature Meter
3 x Calibration packets

Calibration of the pH meter (pls calibrate the PH meter for every use before)
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
