Product detailed description
Calibration solutions are liquids with a known pH value used to calibrate pH meters. Calibration is fundamental for the accuracy of the pH meter and should be done regularly.
For best results, you should use two calibration solutions - one nearing the lower values and one nearing the higher values measured often. For hydroponic farming, growers use a pH 7 and a pH 4 buffer.
pH: 4.01
