How does the meter work?

  • Prior first usage - soak your pH meter in tap water for 12 hours
  • Remove the protective cover
  • Gently clean the electrode with distilled water and dry it off
  • Press the On/off button to start the meter
  • Insert the meter upright into the solution up to the edge and stir gently. Wait a few seconds for the correct value to appear on the display
  • Press the C/F button to switch between Celsius and Fahrenheit
  • Rinse the electrode with water after use and press the On/off button to turn off the meter

We recommend storing the meter in an upright position with KCI storage solution in the protective cover.
