Very compact pressure gauge. Way less potential for leaks. Works great on joblink app.
Game changer. Way fewer leaks. Very compact. Way to measure pressure. The batteries last a long time. It's easy to set up the app called Job Link. It also works well with apple mini iPad. Works fantastic in conjunction with temperature wireless probes

This was a replacement for a set that’s been used “hard” for 3 years.

Well made, usable on a lot of things.
Got these so I didn't have to lug my SMAN 480s everywhere if I didn't have to Very quick to respond on the app, no leakage issues and you don't get a lot of refrigerant build up upon disconnecting from units like you do with standard gouges. I also got adaptors to work on cars which comes in really handy when you're sitting inside the car or to inside the house. You can still look at pressures and Temps, just get a couple of core removal tools to use as a 3 way for both cars and regular hvac systems to charge or evac, and you're good to go. Definitely recommend these or just get the whole set. P.S. the pipe clamps and pyschrometers connect to the SMAN manifolds so you don't need the wired pipe clamps. ... show more
