Information: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 of 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 Commercial Truncheon Nutrient Meter remains accurate.Calibrating the Truncheon Meter is not required but cleaning of the probe is. 'The instrument is only as accurate as the probe is clean' - easy probe cleaning and a quick test is all you need to do to keep the Truncheon Meter operating perfectly for years!
