it does not ..... but the analyzer itself could be affected.Ok. I admit physics is not my thing but how does a change in temperature within a closed system (tank) change the percentage of the mix? ......
More specifically, if you calibrate your O2 analyzer at temperature X and then analyze a gas at temperature Y you could see some difference in your analysis because the O2 sensors ARE affected by temperature.
The amount of this difference between analysis at temperature X and analysis at temperature Y depends on: delta between X and Y, sensitivity of the O2 sensor to temperature and temperature compensation method (or algorithm).
We always recommend to calibrate the analyzer in conditions (temperature, pressure, humidity and gas flow) similar to the ones of the gas to be analyzed.
