The Bluelab Conductivity Pen is a handheld device which is used to measure electrical conductivity in a nutrient solution. Each nutrient that is added to a solution is a salt; the strength of a nutrient is determined by it's ability to conduct electricity through a solution. The Bluelab Conductivity Pen will aid in measuring the overall strength of your nutrient feed so you can make adjustments to ensure that you are not over- or under-feeding your plants.
