Bluelab pH Pen — Quick pH & Temperature Readings in Nutrient Solution The Bluelab pH Pen is a compact, dependable meter for fast pH and temperature checks in nutrient solutions. Keeping pH in the right range is essential for nutrient uptake—if your solution drifts too acidic or too alkaline, nutrients can become less available to plants. Temperature matters, too, since solutions that are too hot or too cold can affect growth rate and plant structure. With the Bluelab pH Pen, you can manage the fundamentals with confidence and keep your crop environment dialled in. Built for everyday use, this hardy handheld meter delivers accurate pH readings in 0.1 pH increments and is fully temperature-compensated for consistent performance. The bright backlit display makes it easy to read in any grow space, and the waterproof body even floats if it drops into the tank.
