The Bluelab Truncheon Nutrient Meter takes the guesswork out of creating the ultimate hydroponic nutrient solutions. This is one of the world's favourite pre-calibrated conductivity meters. Simply brilliant and brilliantly simple.
For the best and repeatable results when growing with hydroponic nutrient solutions, it is essential that you have confidence in the accuracy of what you're feeding your plants. The Bluelab Truncheon Nutrient Meter is a tool that provides peace of mind. It allows you to easily measure the base reservoir water and nutrient/additive additions, so you can be sure that you're feeding optimised nutrients for the stage of growth.
For ultimate nutrient accuracy, remove dissolved salts, that can effect baseline EC/CF readings, and harmful chemicals from your reservoir water using an Reverse Osmosis water filter.
To measure the nutrient solution:
To maintain accuracy, we recommend cleaning the electrodes and testing the meter weekly. Use an Bluelab Calibration & Cleaning Kit.
After feeding your plants, you can check if they're feeding by testing any run off and comparing against the reservoir reading. Run off readings should be lower.
