PH digital tester, PPM digital water tester, 0.05ph high-precision pen-type pH meterThe package includes:
PH meter calibration:
Step 1: Turn on the pH meter and dissoe each buffer solution in 250 mI of distilled water.
Step 2: Immerse the electrode in a pH 6.86 solution. (At a temperature of 25 Celsius).
Step 3: Press the "CAL" (calibration) button for 5 seconds, release-the display will start to flash 6.86-wait until the display stops flashing. Rinse the electrode with distilled water and dry it with filter paper.
Step 4: Immerse the electrode in a pH 4.00 solution. -Press the "CAL button for 5 seconds, then press and release it immediately-The reading will start to flash 4.00.-Wait until the display stops flashing. Rinse and dry the electrode with distilled water as before. Put the meter back in the buffer to test Calibration. If not correct, please repeat calibration
