Answer
A temperature near absolute zero means little to no kinetic energy in the system. To measure the temperature of something, it needs to interact with whatever it is that is being measured. The lack of movement (because of the temperature being near absolute zero) would mean that there is not really any way that the gas would be able to interact with whatever instruments are being used.
