pH, EC and temperature in one pen

The Bluelab OnePen takes the guesswork out of nutrient management. Its replaceable double-junction pH probe resists contamination while titanium EC electrodes deliver stable conductivity readings, and a bright backlit display shows pH and EC side by side with automatic temperature compensation so your numbers stay trustworthy.

Pair it over Bluetooth to the Edenic app to log readings, track trends and share data with your team. With IP68 sealing it shrugs off splashes and dunking, and it floats, making it a reliable everyday tool for hydroponics, coco and recirculating systems. Stocked locally in Windhoek, Namibia for fast delivery.
