Stop guessing and start knowing – the Bluelab OnePen is the only measuring device you truly need for professional results.
Precision & Technology
The Bluelab OnePen is the epitome of reliability. In seconds, it provides you with critical data for your nutrient solution: pH, conductivity, and temperature. By pairing it via Bluetooth with the Edenic App, you can document and compare your readings – ideal for perfecting your plants' nutrient uptake throughout their entire cycle. The robust IP68 casing can even withstand being dropped into the water barrel.
Application & Pro Tip
Handling is incredibly simple: rinse the probe briefly, select the mode, and immerse it in the solution. Once the value is stable, you can save it directly via Bluetooth.
Pro Tip: The lifespan of your OnePen depends on its maintenance. Never use distilled or RO water for storage, as this destroys the ion concentration of the pH probe. Always use Bluelab KCl storage solution in the cap to keep the glass bulb moist. Should the probe degrade after intensive use, you can simply replace it individually with the OnePen!
