Calibration:
STEP 1: Turn open pH meter,disolve each buffer solution in 250ML of distilled water
STEP 2: Immerse the electrode in pH 6.86 standard buffer solution,(under the temperature of 25)
STEP 3: Press the “CAL” button. Wait until the display digital is 6.86pH and steady
STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution
STEP 5: Press the “CAL” button. Wait until the display start flashing is 4.00pH. Then complete pH 4.00 calibration
STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH
How to use:
Step 1-Remove the protective cap from the handheld pH meter. Rinse the electrode with distilled water and let it dry.
Step 2-Press the ON/OFF button to turn on the unit. Dip the electrode in the target solution, making sure the whole electrode is submerged.
Step 3-Stir the solution gently and wait for the value to stabilize. The LCD screen will display both and pH.
Step 4- wipe clean the electrode after using turn off the meter an replace the protective cap.
