PH Calibration and Temperature

Gentlemen:

When calibrating the probe is it temperature compensating. Don't see anything in the code. So should the calibration solutions be kept at close to the tank temp when calibrating, or calibrate with the recommended temp on the solution. ie my 7.0 solution is 7.0 at 77F. or does it really matter?

Not temperature compensated

Thanks, so best to calibrate with the solutions at their recommended temperature.

Actually, it's best to calibrate at tank water temperature. Because there is no temperature compensation, you eliminate the chance of variance of pH if there is a difference between standard and solution to be measured.
