The Bluelab Conductivity Pen (formerly EC Pen) is the ultimate handy solution for measuring conductivity and temperature. Using the same technology that made the bought the Bluelab Truncheon into worldwide fame, the EC Pen is quick and seriously reliable. 


The EC Pen demonstrates the conductivity (TDS/PPM/EC/CF) of your aqueous solution to ensure that your crop is receiving the right amount of nutrition. Like humans, different species of plants have varying nutritional requirements at their different stages of growth. It is imperative as a farmer to ensure you understand the desired and required EC for your farm!
