Essentials 250ml pH 4.01 calibration solution
Essentials pH buffers - used to determine the accuracy of pH meters used to measure the pH of a nutrient solution.
pH Essentials Buffer 4 and 7 is used to calibrate meters. Without calibration, the accuracy of the pH readings given by the meter will be unreliable. This can lead to serious crop losses and, if this condition persists, may cause damage to the plants.
Essentials buffers use two values - 4 and 7 pH - to calibrate your pH testers as they operate at the edge of the pH range where you work in hydroponics, 5.5-6.5. When used in hydroponics, there is no need to calibrate the pH testers to a different value as you are only working in a small section of the pH scale.
When calibrating, it is advisable to use only a small sample of the solution in a separate container, test the meter and then pour out the solution. Pouring out the used solution will prevent possible contamination of the fresh solution and ensure a longer life of the calibration solution.
