Bluelab Truncheon Nutrient Meter — The Original “Dip & Read” EC/PPM Meter The Bluelab Truncheon Nutrient Meter is the original, industry-standard conductivity meter—trusted by growers worldwide for accurate, reliable nutrient readings with zero fuss. Simply dip it into your nutrient solution, and the bright LED lights instantly display nutrient strength in EC, CF, ppm 500 (TDS), or ppm 700, automatically adjusted for temperature. Built tough for daily grow-room use, the Truncheon is fully waterproof, requires no calibration, and is easy to clean and disinfect. Its long-format design also makes it perfect for stirring and measuring in the same reservoir, helping you dial in feeding without slowing down your workflow. Why Measuring EC Matters All plants need the right nutrient strength to thrive. Overfeeding can waste expensive nutrients and stress plants, while underfeeding can slow growth and reduce performance. Conductivity (EC/CF/PPM) reflects the total dissolved salts (ionic content) in your solution, making it the simplest way to track and adjust feeding for healthier plants and more efficient nutrient use. Key Features Industry-standard nutrient meter trusted for decades Measures conductivity: EC, CF, ppm 500 (TDS), ppm 700 Temperature-compensated readings for accurate results No calibration required for hassle-free use Automatically detects liquids—just dip and read Bright LED indicators for brilliantly simple operation Waterproof, robust construction built for long-lasting value Long-format design ideal for mixing and measuring reservoirs simultaneously Easy to clean and disinfect Ideal For Hydroponic growers, reservoir mixing, top-up checks, and anyone who wants a bullet-proof, grab-and-go nutrient meter that works every time—no menus, no calibration, no headaches.
