Hy-Gen pH Buffer 7.0 250ML Calibration Solution for pH Meter 

Hy-Gen pH BUFFER 7 is important as the upper calibrationpoint in the two point’ calibration of electronic meters. Regularly calibrateyour pH meter with both pH BUFFER 4 and pH BUFFER 7 calibration solutions toensure that your meter is operating with precision and accuracy between pH 4and 7.

Monitor the pH on a daily basis. As plants grow, demand fornutrients increase. This means the pH can fluctuate and therefore should betested and adjusted to maintain an optimum working nutrient solution. Nutrientrequirements vary from plant to plant; therefore the ideal pH varies from plantto plant also.
