Essentials pH Meter

The Essentials pH Meter is an essential grow room tool that delivers accurate and reliable pH readings. This allows you to mix nutrient solutions that are bang-on-point, which will help to maximise growth and development. They are designed to be water-resistant and they are built to last. 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. The meter is straightforward to use and has proved to be reliable and accurate, making it great value-for-money.

How To Use

To use the Essentials pH Meter, all you need to do is remove the probe cover, turn on the device and immerse the probe in the nutrient solution that you wish to measure. Wait for the reading to stabilize, and then note the pH level displayed, so that you can adjust the pH levels accordingly.

Regular calibration with pH buffer 7.0 calibration fluid is recommended for maintaining accuracy. To do so, just pour a small volume of your calibration solution into a clean beaker. Dip the probes into the solution, hold the calibration button for a few seconds until the unit has finished calibrating.

Try to ensure that your pH meter is stored properly when not in use. Adding a dash of pH Probe Refill and Storage Solution to the inside of the cap will preserve the integrity of the probes and prolong the unit's lifespan.
