Top Selling Hydroponic pH Meter

Bluelab Handheld pH meter is a sturdy, compact pH and temperature pen. It's a quick, and handy way to manage the success of your crops to ensure maximum uptake of nutrients. A key parameter that affects nutrient uptake is whether your solution is acid or alkaline - this is measured in the pH.

The Bluelab pH Pen measures pH in increments of 0.1 and is fully temperature compensated. The user-friendly meter is fully waterproof, has a backlit LCD display, double-junction probe (not replaceable), a hold reading function, and has automatic temperature compensation. The simple two-point calibration process with 30 day calibration indicator. Other features are a low battery indicator, auto-off function, and a AAA replaceable battery is included.

Bluelab 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. In fact, the fully waterproof Bluelab pH Pen is designed to float when it lands up in your reservoir.

  • One-year peace-of-mind warranty.
  • Automatic temperature compensation for accurate readings everywhere.
