Hy-Gen® pH Buffer 4 Calibration Solution – Accurate Low-Range pH Calibration
Maintaining the correct pH is one of the most important factors in achieving healthy plant growth and maximum nutrient uptake. Hy-Gen® pH Buffer 4 Calibration Solution is a precision-formulated calibration standard designed to ensure your electronic pH meter provides accurate and dependable readings. It forms the lower calibration point in a two-point calibration process and should always be used alongside Hy-Gen® pH Buffer 7 Calibration Solution for the highest level of accuracy.
In most hydroponic systems, the ideal pH range for a nutrient solution is typically between 5.8 and 6.5, with pH 6.3 being a suitable target for many plant species. Maintaining the correct pH allows nutrients to remain available for plant uptake, supporting healthy root development, vigorous growth, and improved crop performance. If the pH rises above or falls below the recommended range, certain nutrients can become chemically unavailable, even when they are present in the nutrient solution. This can lead to nutrient deficiencies, slower growth, and reduced yields.
Over time, pH meters naturally drift and lose calibration accuracy. For this reason, regular calibration is essential to ensure reliable readings. Hy-Gen® pH Buffer 4 Calibration Solution provides the lower reference point required by many electronic pH meters during the two-point calibration process. When used together with Hy-Gen® pH Buffer 7, it ensures your meter accurately measures pH across the entire operating range commonly used in hydroponics, horticulture, aquaponics, laboratories, and water testing.
Manufactured using high-quality analytical-grade ingredients, Hy-Gen® pH Buffer 4 Calibration Solution delivers laboratory-quality accuracy you can trust. Every Hy-Gen® calibration and care solution is produced under strict quality control and formulated under the supervision of a qualified chemist with more than 25 years of industry experience. When precision matters, choose Hy-Gen®—the mark of guaranteed quality for accurate pH meter calibration and dependable growing results.
