I would need to know the model number of the meter you are talking about, in order to tell you if it can be field calibrated or not. A simple way to tell if it can be field calibrated is by looking at the buttons on the display. - If it has only one button (display) it cannot be field calibrated. - If it has two buttons (calibrate & display) it can be field calibrated. @Jared

These typically use only water, however I am evaluating a chiller that would be located outdoors and exposed to subfreezing temperatures and will need to be charged with glycol mixtures. Are there published correction factors for various concentrations of glycol (both Ethylene and Propylene) and at different temperatures? I will need to do some up-front testing, but if I have some idea what to expect, it will minimize the time and expense.
