The Bluelab Commercial Truncheon® Nutrient Meter measures the strength of a nutrient solution, just like the Bluelab Truncheon® Nutrient Meter. The Commercial Truncheon Nutrient Meter however, has been designed for hydroponic crops that require a higher than normal EC or CF requirement during their growing cycle. A reading of up to 6.0 EC or 60 CF is available.
