How to measure the pH of Soil:
Place a small soil sample (about half a teaspoon or teaspoons of soil) on the testing plate provided and a few drops of indicator liquid just enough to stir into a thick paste. Dust the white barium powder from the puffer bottle on to the moist paste. The white powder dusted on the paste changes colour within a minute. Compare the colour developed on the paste with the colour chart provided to the nearest colour & read the pH value. Wash both the plate & mixing rod thoroughly after each test to avoid cross-contamination.

VitaLink Buffer 7 - 250ml
R 135.50
The pH of your nutrient solution greatly affects the availability of nutrients within that solution. pH which is too high or too low can cause deficiencies in essential nutrients that plants need to grow. It can also negatively affect beneficial bacteria in your system or substrate.
The performance of a pH electrode or pH meter will change with time due to aging because as the electrode is used its coating degrades, to ensure it is working correctly, regular calibration is a must. If you are using your pH meter daily, you should calibrate it at least once a week.
To calibrate, use either VitaLink ESSENTIALS Buffer 4 or VitaLink ESSENTIALS Buffer 7. Using both of these buffer solutions will make your calibration more accurate.
The temperature of your solution will also affect the pH value. ESSENTIALS pH Meter has automatic temperature compensation. When calibrating, it is necessary that your pH meter and your calibration fluid have the same temperature. To achieve this, place them in the same room several hours prior to performing calibration.
Available in 250ml and 1L bottles.
