Bluelab Truncheon Meter EC Electrical Conductivity

The Bluelab V2 Truncheon Nutrient Meter is the world’s most trusted tool for measuring liquid fertiliser strength across hydroponic reservoirs, fertigation tanks, and run-off trays. Renowned for its virtually indestructible, fully waterproof build, this heavy-duty baton reader allows growers to measure total dissolved mineral salts accurately and effortlessly - ensuring crops receive optimal nutrient strength without risk of salt burn or under-feeding.

Operating automatically without buttons or switches, the V2 Truncheon turns on when dipped into liquid and turns off when removed. High-intensity blue LED indicators illuminate along the casing scale to display conductivity simultaneously across EC, CF, PPM 500, and PPM 700 scales. With factory calibration locked in, the meter requires zero ongoing calibration adjustments - providing lifetime accuracy out of the box.

Engineered with built-in Automatic Temperature Compensation (ATC), the meter dynamically adjusts for liquid temperature variances to ensure consistent readings. Its ergonomic, heavy-duty housing doubles as a convenient reservoir stirrer, while superior platinum electrodes protected by a slotted shroud guarantee long-term reliability in demanding grow room environments.

Key Benefits:

• Factory Pre-Calibrated: Requires no ongoing calibration adjustments—delivers plug-and-play accuracy every time.

• 100% Waterproof & Durable: Built from high-grade, shock-resistant materials designed to withstand daily drop testing and immersion in reservoirs.

• Multiple Scale Measurement: Displays conductivity simultaneously across EC (0.2–3.6), CF (2–36), PPM 500 (100–1800), and PPM 700 (140–2520).

• Automatic On/Off: Instant liquid sensing turns the unit on upon immersion and powers down when removed to conserve battery life.

• Automatic Temperature Compensation (ATC): Adjusts calculations automatically for temperature changes in liquid feed solutions.

• Dual-Purpose Reservoir Stirrer: Rugged construction allows growers to safely stir nutrients and check conductivity in one easy motion.
