Calibrating for pH at Temperatures Other than 25°C

The observed pH of the buffers (and samples) varies depending on temperature. As a result, it’s important to use pH calibration buffers that have known values at different temperatures (like the MX2500-CAL-4, MX2500-CAL-7, and MX2500-CAL-10 pH calibration solutions), as well as buffers that are at the same temperature as the sample.
