These units have been customer favourites for years and years. They're known for their reliability and robustness, and a lot of growers won't use anything else. How the Essentials Digital pH Meter Works The Essentials pH Meter is equipped with a probe which measures the acidity / alkalinity of a liquid. The tip of the pH meter is dipped into the nutrient solution and switched on. After a short time, the display will settle and the pH of the liquid will be shown on the LCD readout. Once a reading has been taken, the display will lock until another button is pressed, giving you chance to remove the meter from the solution and to read the display. The Essentials digital pH Meter is water-resistant and will not be damaged if accidentally dropped into a solution for a short space of time. Calibration is a simple push-button operation, and the unit has an auto switch-off facility to preserve battery life.
