Bluelab Conductivity Pen
The Bluelab Conductivity Pen is a compact, professional-grade nutrient meter designed to accurately measure EC (Electrical Conductivity), TDS (Total Dissolved Solids), PPM, CF, and solution temperature. Built using the same trusted technology that made the famous Bluelab Truncheon the industry’s benchmark, the Conductivity Pen delivers fast, accurate, and reliable readings in a convenient handheld design.
Whether you’re growing in hydroponics, coco coir, soil, or other soilless media, monitoring nutrient strength is essential for healthy plant growth. Different plants, and even different stages of growth, require varying nutrient concentrations. The Bluelab Conductivity Pen allows growers to quickly check nutrient solution strength, helping prevent overfeeding, underfeeding, nutrient deficiencies, and plant stress.
One of the standout features of the Conductivity Pen is its ability to measure both conductivity and temperature in a single instrument. Temperature directly affects EC readings, so the pen incorporates Automatic Temperature Compensation (ATC) to ensure highly accurate results regardless of water temperature.
The bright backlit LCD display is easy to read in all lighting conditions, making it ideal for use in grow rooms, greenhouses, and commercial facilities. Users can select their preferred measurement units, including EC, CF, PPM500, PPM700, and Celsius or Fahrenheit, allowing compatibility with nutrient feeding schedules from around the world.
The Bluelab Conductivity Pen is fully waterproof, making it suitable for daily use around reservoirs, nutrient tanks, and irrigation systems. While calibration is optional, the pen includes a successful calibration indicator, ensuring confidence in every reading. Additional features such as the hold function, low battery indicator, and automatic power-off make it simple to use while maximising battery life.
For more than 30 years, Bluelab has been designing precision water monitoring equipment trusted by professional growers in over 100 countries. The Bluelab Conductivity Pen continues that tradition by providing growers with dependable nutrient monitoring in a compact, portable format.
