hi ericW,
it depends on what point in the system you want to measure.
- evaporator
- compressor

Hi,

Superheat for the various ranges of evaporated
6-8K for air conditioning
8-10K for the cold
10-13K for freezers
4-6K has no such scope as the oil starts to less than 6K on tight foam which means a large number of factors in the oil.
The gas is of no significance.
