Start measuring pH of your solution

Step 1
Remove storage cap, press power button to turn on

Step 2
Our pH meter is pre-calibrated. Place probe tip in solution. Wait for the measure to stabilize and take reading

To record/hold the measurement, short press hold button

Step 3
Rinse probe tip in fresh tap water after each use. Press power button to turn off and cover the storage cap

Note After Use: Keep the probe tip wet by adding water to sponge in storage cap for better performance
If the pH reading is different from what you expected, you can deep clean the probe first and calibrate

Switch to measure TDS, EC of your solution

Short press to MODE button change between pH, TDS, EC modes

Start pH calibration 

pH calibration is not required before first use as it is pre-calibrated. If the reading is different from what you expected, or after long-term storage, you can calibrate using the following instructions.

Step 1
Prepare pH 6.86/4.00/9.78 standard solutions. Measure 250ml distilled water. Dissolve solution powder in a container. Calibration should starts with 6.86 standard solution.

Step 2
Resin probe tip in clean water and shake off any excess water.

Step 3
Place probe tip in fresh pH 6.86 standard solution until the reading is stable. Reading should be within range of 6.06-7.66

Long press Mode/Cal button, display shows ‘CAL’ 

Short press Mode/Cal button to select ‘6.86’. Leave the probe in solution while the display is flashing. When the display stops flashing, pH 6.86 calibration is  successful. 

Step 4
Repeat calibration in pH 4.00 and pH 9.18 standard solutions.

If the display stops flashing and shows “Err’
pH calibration failed, please re-calibrate or prepare fresh standard solution. Or contact us for further assistance.
