The world's favourite nutrient meter!
With its super tough, high quality, fully waterproof design, no calibration required, daylight readable blue LEDs and no on/off buttons to worry about, the Bluelab Truncheon® Nutrient Meter has proven itself as the world's favourite nutrient meter.
The Bluelab Truncheon measures the nutrient strength of a solution. It is essential when growing hydroponics to KNOW what the strength of the solution is before feeding your plants AND while they are growing. To take a reading of your solution - simply place the probe head into the solution for 1-2 minutes to reach the same temperature as your nutrient. Remove from the solution and place back in to take the reading as indicated by the flashing lights. Rinse the probe after use in fresh water and clean once a week to ensure the Truncheon remains accurate. It's great for stirring your nutrient tank too!
