The Apera Instruments Calibration Buffer Solution is color-coded and standardized against NIST certified pH references within 0.01 pH at 25°C (77°F). It’s ideal for the calibration of pH meters/testers that can automatically recognize pH 1.68 standard e.g. Apera PH60, PH700, PH800, PC400S. Since pH level is affected by temperature, a temperature/pH reference chart is provided on the bottle label for reference.
Store at room temperature and away from direct sunlight. Keep the bottle tightly closed when not in use. Keep out of reach of children.
