Essentials PH Meter

Essentials pH Meter is excellent little hand-held device for measuring the acidity/alkalinity of your nutrient solution. Reliable and great value-for-money.

  • Gives a digital readout of the pH of your nutrient solution.
  • Made of strong plastic
  • Reliable and accurate
  • Easy push-button calibration
  • Water-resistant case
  • Auto shut off to save battery life

How the Essentials Digital pH Meter works:

The Essentials pH Meter contains a special probe which measures the pH of a liquid. The end of the meter is dipped into the nutrient solution and switched on. After a short time, the display will settle and 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. The meter is straightforward to use and has proved to be reliable and accurate making it great value-for-money.

Using the Essentials Digital pH Meter

To grow plants successfully, particularly in hydroponics, it is necessary to monitor and adjust the pH of your nutrient solution on a regular basis. In general, plants grown in hydroponics like a pH of approximately between 5.5 and 6.5 (plant species dependant) with a little bit of variation within this range. This is because plants can only absorb certain nutrients at a pH close to 5.5 and others at a pH closer to 6.5.

If your nutrient solution strays out of this optimum range for too long, your plants will not be able to absorb all the nutrients that they need and will become deficient, leading to slowed growth and eventually sickness. To avoid pH problems, and the plant problems that it can cause, it is wise to check and adjust the pH of your nutrient solution very regularly (every day if possible). Soil grown plants tend to like a pH of around 6.5. A good way of finding out the pH of your soil is to test the run-off water which comes out of the bottom of the pot when you water.

Before using

for the first time, the Essentials Digital pH Meter needs to be calibrated. A small single-use sachet of calibration fluid is supplied with the meter for this purpose. The meter should also be re-calibrated once a week if being used daily. Calibration fluids are available at OSGS for this purpose. To then calibrate the meter, remove the black protective end-cap and wet the probe with clean water. Shake out the end to remove excess water and dip into calibration fluid. Pressing the calibration button will then begin the automatic calibration process. When this is complete, your Essentials Digital pH Meter is ready for use.
