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 into nutrient, 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!
