Product Information

All plants need access to the right amount of food (nutrients) so that they can grow and thrive. Over- or under-feeding your plants can result in the waste of expensive nutrient resources.

The easiest way to keep track of the amount of nutrients in your solution is to regularly measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.

Measuring the temperature of your solution is equally important, as - if it’s too hot or too cold - this can affect the plants’ growth rate and structure.

Providing quick and accurate readings at the click of a button, you can rest assured that the user-friendly Bluelab Conductivity Pen will give you reliable results, every single time.

In addition, this product offers a range of in-built measurement units, so you’ll be able to customise it according to your preference. For conductivity readings, you can choose between EC, CF, PPM 500 (TDS) or PPM 700; for temperature, you can select ˚C or ˚F.

  • Fully waterproof, not just water-resistant
  • Selectable measurement units so you can customise with your preferences
  • Flat electrode for easier cleaning and maintenance
  • Hold reading function to capture every measurement with ease
  • Automatic temperature compensation for accurate readings anywhere
  • Auto-off function to extend battery life
  • 1 x AAA alkaline battery included, getting you started immediately

Directions of Use

Using the Bluelab Conductivity Pen

  1. Press power button to turn on.
  2. To measure conductivity Place probe in solution and wait for reading to stabilize.
    To change units of measurement hold down the units button for 3 seconds until the conductivity and temperature units start flashing. Short press units button again to cycle between unit combinations. To exit this mode don’t press anything for 3 seconds. 
    To hold reading If you want to “hold” the reading on the screen, short press the power button. To exit the hold function press the power button again. 
  3. To change units of measurement hold down the units button for 3 seconds until the conductivity and temperature units start flashing. Short press units button again to cycle between unit combinations. To exit this mode don’t press anything for 3 seconds. 
  4. To hold reading If you want to “hold” the reading on the screen, short press the power button. To exit the hold function press the power button again. 
  5. To turn pen off Press and hold the power button until OFF is displayed.
The probe needs to be cleaned once every two weeks to ensure accurate readings.

NOTE: You can change units while in hold mode by holding down the units button. Rinse conductivity probe To reduce the build up of nutrient salts, rinse under running water after each use.
NOTE: The pen will automatically turn off after 4 minutes to conserve battery power.
