Labnox pH Buffer Solution ph 7.00 | pH Liquid Calibration at 25°C 500 ml Solution Basin  (Pack of 1)

Using a high-grade buffer to calibrate your meter before each use is the only tried-and-true way to get the most accurate results every time. pH calibration solutions, also called pH buffers, are an essential tool when measuring pH with a pH meter and electrode. While some users will try to make their own solutions to save money, these homemade buffers are not accurate or stable, and in the end they will waste time and interfere with the accuracy of your results.
