The Bluelab Truncheon Nutrient Meter is one of the most trusted EC meters used in hydroponics. Known for its simplicity, durability and reliability, it allows growers to quickly measure nutrient strength and ensure plants receive the balanced feed they need throughout the grow cycle. Unlike many EC meters, the Truncheon requires no calibration. It comes factory calibrated and maintains accuracy through simple probe cleaning, making it one of the easiest nutrient monitoring tools available for growers. The long-format design also allows the meter to be used to stir nutrient reservoirs while measuring EC, making mixing feeds quicker and easier in busy grow rooms. Fast, Accurate EC Measurement Simply immerse the probe into your nutrient solution and read the measurement from the flashing LED display. The Truncheon measures: EC (Electrical Conductivity) PPM 500 scale PPM 700 scale CF With automatic temperature compensation, the meter adjusts readings based on nutrient temperature to ensure consistent accuracy. Built for Hydroponic Grow Rooms Designed specifically for hydroponic nutrient solutions, the Bluelab Truncheon is fully waterproof and built to withstand everyday use around reservoirs and mixing tanks. No calibration required Fully waterproof construction Automatic temperature compensation Easy-to-read LED indicator lights No buttons or switches Auto power off to conserve battery Powered by AA batteries 5 year manufacturer warranty Designed and manufactured in New Zealand Running Higher EC Levels? If you run stronger nutrient feeds and need a wider measurement range, take a look at the Bluelab Commercial Truncheon. It measures nutrient solutions up to 6.0 EC, making it ideal for heavy feeding regimes and commercial grow environments. For most hydroponic growers, the standard Truncheon remains the perfect combination of accuracy, reliability and simplicity.
