Growth Technology pH Buffer 4 and 7 is a simple but essential calibration kit for pH meters. Each solution is made to a known and fixed pH, allowing you to calibrate your meter correctly and help maintain consistent accuracy over time. For growers working with nutrients, reservoirs, feed tanks and irrigation water, regular pH calibration is an important part of dependable crop management.
This kit contains one 300ml bottle of pH Buffer 4 and one 300ml bottle of pH Buffer 7, giving you the key reference points commonly used when calibrating handheld and portable pH meters.
pH meters can drift over time through normal use, storage conditions and repeated testing. Using fresh buffer solution helps confirm that your meter is reading correctly, so you can make better decisions when adjusting feed strength and nutrient balance. In practical day-to-day growing, that means more confidence in the readings you rely on.
This calibration kit is supplied as a twin set, making it convenient for growers who want both commonly used calibration points in one pack.
Growth Technology pH Buffer 4 and 7 is suitable for growers using pH meters in hydroponic systems, propagation areas, grow rooms, greenhouses and general horticultural setups. It is useful wherever nutrient solution, reservoir water or irrigation water needs to be monitored accurately.

Use clean containers and avoid contaminating the buffer solutions during calibration. Follow the calibration instructions provided by your pH meter manufacturer, as procedures can vary slightly between models. For best practice, calibrate your meter regularly, especially if it is used often or has been stored for a period of time. After calibration, proper probe care can help maintain accuracy between checks.
If you also monitor nutrient strength, you may want to pair your pH tools with an EC meter such as the AQUALINE EC TRUNCHEON.
