Bluelab pH Pen Product Description: The Bluelab pH Pen is a high-quality pH meter that provides reliable and extremely accurate measurements of the current pH value and temperature of your nutrient solution. The backlight ensures that the display is always easy to read. The pH Pen is waterproof, features dual pH electrodes for particularly precise measurements, and a hold function. The hold button allows you to save the current value and display it on the screen until the hold button is pressed again. pH meters should be calibrated regularly, and the Bluelab pH Pen offers a special calibration function for this purpose, making the process quick and easy.
