Bluelab EC pen

The handheld measuring device Bluelab EC Pen is designed for measuring temperature, ppm, or EC in (nutrient) solution. Daily EC value measurements ensure that your plants will not suffer from excessive concentration or dilution of the solution and will always have the optimal amount of nutrients.

The fully waterproof Bluelab EC Pen measuring device allows you to choose between units for measuring conductivity (EC or ppm) and temperature (Celsius or Fahrenheit). It requires calibration, but temperature compensation is automatic.

Another advantage of this pocket meter is the clear backlit display and operation on a single AAA battery, which is included. You will be alerted to low battery with a flashing light. It also has an automatic shut-off feature when not in use. You can view the exact specifications in the image gallery. The probe is not replaceable.
