pH Buffer 4

Use VitaLink Buffer solution to calibrate your pH meters. The pH of your solution greatly affects the availability of nutrients within that solution. pH which is too high or too low can cause deficiencies in nutrients that plants need to grow.

It can also negatively affect bacteria in your system or substrate. The accuracy of a pH meter will change with time due to aging, its electrode coating degrades over its period of use. 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 Buffer 4 or VitaLink Buffer 7. Using both of these buffers will make your meter more accurate.

The temperature of your solution will also affect the pH value. 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.
