GH pH 7.01 Calibration Solution 8 oz


You need to test your pH so you can adjust it for maximum growth and yield, but a pH meter is only as good as its last calibration—kind of like setting the tare button on a scale, you need to come at pH from an accurate starting point.

General Hydroponics 7.0 Calibration solution is easy to use. Pop your probe into the solution, and adjust the meter to read 7.0 and you’ll be on your way to getting the correct reading, every time.

Pro-tip: Looking for an excellent pH meter to use in your garden? Check out the Blue Lab pH Pen.


This solution is all your customers need for calibration of their pH meter. They simply dip the probe in a small amount of the balanced solution, adjust the meter to read 7.0, and they're ready to go.
