Mollier diagrams

[TF12]

Hey,
Wanted to see what thoughts everyone had about using Mollier diagrams in the field, as a mechanic, operator, maintenance etc.
Is it a good practice or does anybody besides engineers use it?

As a technician I find that it serves no purpose. A PT Chart on the other hand is a useful tool.

As a technician I feel the same way. I could see it maybe as a point of reference, maybe at startup to compare operating conditions to down the road...
