Regular calibration of your pH meter is essential to ensure accurate readings. Essentials pH Buffer 7 is used to calibrate your pH meter, by providing a solution with a known pH level of 7. To use, pour a small amount of the solution into a clean vessel, and then immerse your meter’s probe into the solution.
Tap the probe to remove any bubbles, and allow a few minutes to finalize the reading. You can now manually adjust your pH meter to read 7.0, or select 7 from the meters calibration settings if available.
