A compact and robust handheld solution

Everyday accuracy of the fundamentals

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.

  • Fully waterproof - not just water resistant
  • New Zealand-made quality, built for growers

  • Simple two-point calibration process for accuracy
  • Automatic temperature compensation for accurate readings everywhere
  • Auto-off function to extend battery life
  • Our 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.

    The Bluelab pH Pen was designed and built in New Zealand. Tried and trusted by growers all over the world, this essential tool is one of our top-selling products.
