Fast and accurate measurement: Just put it on, immerse in the liquid, and read the display, no color chart or test paper is needed; the large digital display makes it easy to read.
Automatic calibration: without any adjustment screwdriver, just use the automatic calibration button and the attached buffer powder to complete the calibration.
ATC function: Automatic temperature compensation automatically considers temperature changes.
Portable design: Hand-held pen type and compact carrying case, which can be easily put into a pocket or purse and carried with you.
Wide range of applications: very suitable for home and laboratory pH testing applications, including drinking water, swimming pools, aquariums, hydroponics, etc.

Weight: 50g/1.7oz
calibration:
1. Switch PH meter
2. Dissolve any buffer solution in 250ML distilled water
3. Immerse the electrode in a solution with a pH of 6.86 (temperature below 25)
4. Press and hold the "CAL" (calibration) button for 5 seconds, then release
-The display will flash 6.86
-Wait until the display stops flashing.
Rinse the electrode with distilled water and wipe dry with filter paper.
5. Immerse the electrode in a pH 4.00 solution,
-Press and hold the "CAL" button for 5 seconds, then immediately press the second time
-Reading will flash 4.00
-Wait for the display to stop flashing
Rinse and dry the electrode with distilled water as before.
6. Put the meter back in the buffer solution for test calibration. If it is not correct, repeat the calibration.
