Growth Technology pH 7 Buffer 300 ml, calibration solution

Calibrate pH meters and nutrient solutions with pH 7 buffer

This pH 7 buffer solution is designed for verifying the accuracy of pH meters and for measuring the pH of nutrient solutions. Regular calibration with Growth Technology Buffer 4 and 7 is essential to prevent unreliable pH readings, which can cause significant crop loss and plant damage.

This buffer is ideal for hydroponics, where working within the 5.5–6.5 pH range requires precise calibration. Use only a small sample for calibration in a separate container, discarding it afterward to prevent contamination and ensure the longevity of the fresh solution. This method guarantees more accurate pH measurements.
