The handy Bluelab EC Pen is a measuring device for determining temperature, ppm or EC in (nutrient) solutions. Daily EC measurements ensure the optimal nutrient supply to your plants in order to avoid over- or under-fertilization.
Fully waterproof, the Bluelab EC Pen offers a choice of EC or ppm units and Celsius or Fahrenheit temperature display. Calibration is required, but temperature compensation is automatic.
Other features include the illuminated display, operation with an included AAA battery and automatic shutdown when inactive. The exact specifications can be found in the image gallery. The probe is not replaceable.
