Description

pH Meter Calibration Solution

The calibration solution includes 4 oz each of 4.00 and 7.00 buffers. These solutions are repackaged from bulk quantities to get you the best pricing. For testing, pour each buffer into a separate small glass. You do not want to stick the probe of the pH meter into the buffer jars directly because you will eventually sacrifice the accuracy of your buffers. Use these buffer solutions with the Beverage Doctor pH Meter.

Expires after 6 months if unopened. Expires after 3 months if opened.
