Why 500 Micron Gauges Yellow Jacket Is Necessary
I’ve found that a 500 micron gauge is necessary because it gives me a much more accurate picture of how deep a vacuum I’m actually pulling. When I’m working on HVAC or refrigeration systems, guessing is not good enough. A Yellow Jacket gauge helps me confirm that moisture, air, and non-condensables are removed properly, which protects the system and helps it run the way it should.
