Description
Bluelab – EC Truncheon
The Bluelab EC Truncheon is the industry’s most trusted nutrient meter, built to deliver unbeatable accuracy, durability, and ease of use. Engineered for growers who demand long-term reliability, the Truncheon features a rugged, waterproof design that can withstand daily use in any grow room. With its long-format body, you can stir and measure nutrient reservoirs at the same time, making feeding quicker and more efficient.
This meter automatically activates when placed in solution and displays readings using bright, easy-to-see LEDs. With support for all major conductivity scales—including EC, CF, PPM 500 (TDS), and PPM 700—it provides instant, reliable insight into your nutrient strength. No calibration is required, and cleaning is quick and simple, giving growers a maintenance-free tool that lasts for years.
Conductivity monitoring is essential for preventing overfeeding or underfeeding. By ensuring your nutrient solution contains the ideal amount of dissolved salts, the Bluelab Truncheon helps maintain consistent plant health, optimal nutrient uptake, and superior growth.
