Robinair AC Manifold gauge set was originally for R12, it has been adapted for 134A

To properly diagnose an AC system the use of a manifold gauge set is needed. AC gauge pressure readings help professional auto technicians determine if the system is low and exactly what is going on with the car’s A/C system. A 134A gauge set is also used when attaching a vacuum pump to the car for evacuating/removing the air out of AC components. If air is left in the system, the moisture it contains combines with refrigerant under pressure can cause a corrosive acid to form that can destroy evaporators, condensers or even the AC compressor from the inside.

However, adding refrigerant isn’t always the solution for car air conditioning problems and troubleshooting may be required before just charging a car AC system.
