To get the proper use of your expensive pH monitoring equipment, it is vitally important to recalibrate it periodically with a buffer and maintenance solution with a known pH level. These premium quality buffered solutions from Hanna Instruments solve that problem. They have a pH of 7.01 when the contents are at 25 Celsius, with accuracy of +/- 0.01 pH, and the packets come with a table indicating what the solution's pH would be at temperatures ranging from 0C to 85 (32 to 203F) (which vary accordingly, depending on the conditions you actually do the calibration test in).

Product Notes:

Hanna's technical calibration buffers have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet.
