Fieldpiece is laser-focused on creating products that empower HVACR professionals - today and tomorrow. Visit the Store Visit the Store Visit the Store Visit the Store Visit the Store Fieldpiece’s laser focus on continuous improvement, coupled with years of feedback from HVAC and refrigeration specialists, has resulted in the SMAN Refrigerant Manifolds – the most advanced digital refrigerant manifold on the market. Our wireless refrigerant manifolds have an extremely rugged overmold casing, reinforced hook, hermetically sealed sight glass, data logging, and tightness test so you can do your job easier, faster, and better. A digital refrigerant manifold is one of the most important HVACR tools as they are used to measure system pressures and temperatures in an HVACR system. Manifolds and vacuum gauges can be used for both diagnostic and servicing purposes. Our SM482V is packed with the features you need to get the job done – easier, faster, and better. Plus, it works with our wireless scale, pipe clamps, and psychrometer and integrates seamlessly with our Job Link System App. SM482V VC1G VC2G SR47 VP87 SC680

  • High quality. App lets you monitor the outside, while you're working inside.
Model: SM482V
What can I say? It's Fieldpiece, so obviously a high quality set of digital gauges. If you DL the joblink app, you can monitor the gauges on your phone, which is handy if you're in the attic with a coil, trying to monitor subcool or vac or whatever from the gauges outside.

  • Great manifold. Should use as a backup vacuum system instead of main, though.
Model: SM482V
Works great. Upgrading my entire AC setup so I'm ready to go into business when the time comes. This manifold I paired with the Fieldpiece Joblink set which includes the wireless air temperature sensors for return/supply, pressure sensors for suction/liquid, and temperature clamps for suction/liquid. One issue I had initially was on system vacuuming, and I almost returned these for the 3 port SM382v, but decided against the return. The issue is present when using hoses and manifolds that have had refrigerant ran through them. When pulling a vacuum, refrigerant will start to evaporate at inconsistent times. This leaves you wondering if that 5 micron delta/min on a decay test is a leak or not. Most of the time, it did a great job of pulling down to 200 microns (manifold side) then on closing the manifolds vacuum port, we'd shoot up to about 350 or 400 while it equalized. After equalizing, we'd see a constant ~2 to 5 micron rise per minute. Other times, I'd get down to 400 microns and pop back up to 520, and it would pump back down to 390 and pop back to 510, pump down to 380 and pop back to 500. This cycle repeats itself and I can't tell if it's a micron gauge fault or evaporation. It isn't a leak, because it holds solid microns, but it does pop around quite a bit. Purge with nitrogen through your manifold and lines at high pressure before starting vacuum to mitigate this. Instead of returning this manifold because of the vacuum inconsistencies, I went for the redundancy approach and got two large vacuum hoses and a wireless micron gauge, leaving the manifold for watching system charge or vacuum alternative. Although I could just use the full wireless set for that now, anyways. ... show more

  • High quality
Model: SM482V
Extremely quality made. Lots of features. Has vacuum guage built in, a good one. I'll update review as I use it more. I think the logging feature is important.
