R-7062 pH Standard 7.2 (2 oz)

This R-7062 pH Standard can be used in place of pool water in the pH test to confirm the acccuracy and reliability of your testing methods. The standard solution is calibrated to 7.2 pH and there are 2 ounces in each bottle. Use the R-7062 standard (7.2 pH) in place of pool water in your comparator block. The expected result is exactly pH 7.2, so you can use this standard to “calibrate” your eyes to read the test more effectively.
