This user-friendly and hardy handheld pen will take measurements in increments of 0.1 pH and is fully temperature compensated, so you can expect accurate readings every time. Bluelab's products are designed and built for grower environments not the lab so you can relax knowing that your pen can withstand the knocks, drops and deep-water plunges that come with everyday growing.
The fully waterproof Bluelab pH Pen is designed to float when it lands up in your reservoir.
Healthy growing plants, just like humans, need a balanced diet of appropriate nutrients (food). However, plants can only access these nutrients when the nutrient solution is within a certain pH range. To help your plants thrive, get the fundamentals right by measuring pH and temperature to ensure that these are always in the optimal range.
