- Automatic calibration: It has a built-in calibration function for 2 kinds of buffer powders, and calibration can be completed by pressing a button. This PH meter has been calibrated at the factory. Users can use it directly.
- Fast and accurate results: no need to use those annoying color cards and test strips. Resolution: 0.01 pH, accuracy: 0.01 PH.
- Compact and portable design: Pocket pH meter, light weight and compact structure. It is completely hide in your bag or pocket, suitable for carrying with you.
- About the PH pen calibration method:
(1) First take about 250ML of neutral water (preferably distilled water or pure water) (try not to use tap water or mineral water or mountain spring water, otherwise it will affect the data)
(2) Add calibration powder 6.86 (the green package), stir evenly to fully dissolve it.
(3) Remove the protective cover of the test pen-power on-immerse the probe in the prepared calibration solution, first look at the reading. If the data is consistent with 6.86 or the deviation is small, no calibration is required. If the value deviation from 6.86 is relatively large, press Press the CAL button for three seconds, let go after the screen flashes, and the automatic calibration is in progress. It is expected that after 5 seconds.
When the display shows END, the calibration is complete. Take out the ph pen and clean the electrode with distilled or purified water to absorb the liquid.
(4) Use the same method for 4.00 calibration powder.
(5) Generally, only two packs of calibration powder 6.86 and 4.00 are needed, and 9.18 calibration powder is not required.
