Simply turn the meter on, dip the tip of the meter in the solution you are measuring, allow the reading to stabilise on the LCD screen and then withdraw it to take your final reading.

The reading can be changed between E.C, ppm 500 or ppm 700 scales at the push of a button to suit growers in all parts of the world.

The EC Pen also doubles as a temperature meter and provides readings in degrees Celsius (°C) or Fahrenheit (°F) .
