For those who suggested that a pH meter needs to be temperature
calibrated to the nth degree. I had an "Old Fart" gut feel that for
home gardening it was not necessary. The following is a response
to the question following.
Just thought a "second opinion" was needed
In this case nothing snipped for clarity

A quick solution to this question is to place the probe in the solution
and wait a couple of minutes. The probe will heat or cool to the
temperature of the liquid and give you an accurate reading. For home
gardening, the small +/- error would be negligible.
