I have two gauges. SMAN4 that I use for new system, evacuating and charging. Then a cheap yellow jacket I carry for quick check up and for rooftop units. Would rather risk dropping cheaper gauges than $450 ones.
I wish my HS33 limited edition had wireless capabilities on its amp clamp, would be handy for when I need to test it out on condensers who's disconnect is far away. Guess I can still disconnect the lie voltage on contactor and manually go from there lol.
SRS2C it's really good too, my beef with it is that it sometimes does not sync.
Now I need to see on why my vacuum pump won't pull down much. Even have thread locked the unused ports.
