  3. Turn on the device by pressing the ON/OFF button.
  4. Dip the probe head into your target solution and ensure that it is fully submerged for better accuracy.
  5. Stir it gently and wait for the value to stabilize. Both the temperature and pH readings will display on the LCD screen. 
  6. Press "CAL" to switch between Celsius and Fahrenheit temperature units.

Tips for pH calibration:

  1. Start off by preparing 3 separate beakers containing a pH 4.00, pH 6.86 and pH 9.18 solution respectively. For better accuracy, make sure each solution is 250ml and at a stable temperature of 25°C.
  2. Prepare 3 separate beakers with distilled water in advance for probe head cleaning purposes.
  3. Immerge the probe head into a beaker with distilled water and stir it for approximately 5-10 seconds and spin-dry it.
  4. Press the ON/OFF button to turn on the meter.
  5. Remove the protective cover and immerse the probe head into the pH 6.86 buffer solution. Stir gently and wait for the value to stabilize.
  6. Press and hold the "CAL" button for about 5 seconds when the reading on the LCD screen displays the same value of pH 6.86.
  7. Rinse the probe head with distilled water and blot dry. Repeat the same for the other 2 solutions.
