The Bluelab PH Pen is the latest innovation to provide you with a handheld tool that will accurately measure the PH value of your nutrient solution that you supply to your plants.

This clever little device has automatic temperature compensation, so you can dip it and read it straight away. It displays the readings on a back lit LCD screen which has a hold function for you to easily view your reading, which ranges from 0.0 - 14.0 PH and it also read's the temperature of your water and can display the reading in Celsius or Fahrenheit.

The Bluelab PH Pen is fully water proof and has a low battery warning and an automatic off function, by far the best PH Pen your money can buy.
