Still one of the most reliable meters on the market. With a conductivity range right up to 6.0EC (60CF or 4200ppm), it will never leave you short. The Commercial Truncheon® Nutrient Meter has been designed for hydroponic crops that require a higher than normal EC or CF requirement during their growing cycle.
Its super tough, fully waterproof, has no on/off buttons to worry about and does not need calibrating. Its great for stirring your nutrient tank too! It is essential when growing with a hydroponic solution to know what the strength of the solution is before feeding your plants and while they are growing. This is easy when you use the commercial Truncheon!
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 month to ensure the Truncheon Nutrient Meter remains accurate.
