Bluelab EC Meter

Imagine investing in premium nutrients for weeks, only to see your plants suffer deficiencies or burns due to one simple issue: you don’t know the true salt concentration in your solution. Electrical conductivity (EC) is the key to understanding your plants’ nutrient intake, but measuring it with unreliable tools can ruin entire harvests. The Bluelab Conductivity Pen solves this: a portable, trustworthy device that eliminates guesswork, letting you adjust feeding with exact data and avoid costly mistakes.

Technology at the Service of Cultivation

Equipped with a high-sensitivity graphite sensor, this meter detects minute variations in nutrient concentration (0.0–20.0 mS/cm range), even in diluted solutions for clones or seedlings. Automatic Temperature Compensation (ATC) adjusts readings to 25°C, ensuring accuracy in cold environments (like basements) or hot ones (under LED lights).

✔️ Waterproof: Handles spills, quick cleanings, or accidental drops.
✔️ Backlit display: Clear readings in low-light conditions.
✔️ Long-lasting battery: 500 hours of continuous use without charging.
✔️ Dual EC/TDS scale: Switch between mS/cm, ppm 500, and ppm 700 with one button.
✔️ Easy calibration: Adjust with the included 2.77 mS/cm solution in under 2 minutes.
✔️ Certifications: CE and RoHS compliant for safety and durability.
