Bluelab Truncheon

The Bluelab Truncheon nutrient meter is an essential tool in hydroponics, horticulture, and floriculture for measuring the concentrations of solutions before feeding and while plants are growing. This meter measures EC and CF units on the 500 and 700 PPM scales. To take a reading of the solution, simply place the waterproof probe into the solution for 1 to 2 minutes to allow the probe to reach the same temperature as the nutrients.
