The reading still changes with the angle it is viewed at, or which eye you are squinting at it with.
Then there is the PT chart interpolation error.
With digitals, you don't even have to look at pressure, you get a direct saturated temperature reading, which is what you really need.
There is a 9 year span in instrument ages in this picture. They are from 3 different manufacturers, use 4 different types of pressure transducers, and 4 different types of 3 different technologies of temperature sensors.
There is only about a 1.5 psi difference between the lowest and highest pressure reading, and 1.1º difference in the temperature probe readings among the 4 instruments that have temperature probes. The BTD-1000(top left) has no temperature probes.

I'd put some money on the table that says my Digi-Cool DRSA-1250 would still work fine. The manifold it is mounted on may need to be replaced though.
My BTD-1000 has survived such a drop, onto concrete.
