Elitech PT-500/800pro Digital Manifold Gauge with APP Control, Auto Superheat/Subcool Calculation, Compatible with 140 Refrigerants, for HVAC AC Refrigeration Maintenance

I have 4 sets of these between my crew and everyone loves them. Tried the NAVAC ones because they have wireless temp sensors, only to find out the NAVAC ones don't calculate SH/SC and you cant view the temps and pressures at the same time in the app. Elitech is the way to go for price and functionality. I do wish the body was more study, we beat these things up in the field and I have had a few crack where the head meets the neck, they still worked but I replaced them. Again, they were dropped and abused, but if they had a full metal body these things would last forever. I recommend pairing them with Hilmor stubby hoses and C&D Valve CD2060 Large Thumb Screw Core Depressor attaches to 1/4 M.

Very useful and accurate

I'd claim false advertisement on the box, the one pictured is not the one you get, the fittings don't have individual slots and move around, added foam to quiet the box and protect scratching of screens. T fitting leaked out of box had to put new Schrader valve in. App requires lots of refreshing sometimes to find devices. Overall not bad for price, but honestly expected a little more.

Works as advertised. Easy to use.

Works great and very accurate

These gauges appear to b e well made but after trying to access some way to load the phone app for several hours, I gave up. To me, the gauges are no better than my existing analog gauge set without the phone app. Could not access the manufacturers web site and checked all the app stores for the software, but no success. Too bad, because the gauges would have been a good value.

I decided to give these gauges a try. The weak point on them is the jacks for the temperature probes and the probes themselves. See the screenshots . It isn't very great when only one of the temp probes and gauges is working. Instead of using a standard type k setup this set uses a proprietary setup with a stereo jack type connection. The issue is this gets in the way when the gauges are connected to an hvac system. If the jack were on the top this might not be an issue, but I first had one probe start to fail about half the time and then the other gauge seemed to have an issue with the female port for the jack. The app can be troublesome when connecting them. I'd have to close it and turn my phone on airplane mode while power cycling the gauges and then hitting the connect button on them after reopening the app. I contacted elitech three times when the temp probes stopped working but never heard back. So I opted to return them since I was within the 30 day window and the lack of response from the mfg made the 1 year warranty pretty useless. Also, other things to note about these. The seals aren't standard gauge type seals. I noticed them starting to wear after two weeks. Since they aren't standard this would require getting new seals from the mfg. The charging tee that's included also uses a non standard valve depressor. Mine came off and I was unable to replace it with one from the assortment of hose repair parts I keep with me. Every other hose, valve, and adapter I've used has been interchangable with the parts kit I carry. I ended up buying expesive appion charging tees to keep using this kit The gauges use npt and you have to use tape to seal the connection. You'll need to have some bent adapters or tees on hand to make these work with most Lennox or goodman systems and some carriers due to fitment issues with the straight connector. I liked these when they were working, but have now switched to fieldpiece probes and wireless temp clamps. I borrowed a set from a friend and noticed I didn't have the fitment issues or pairing issues. The elitech app seems nice enough. It's visual and was nice to screenshot, but the pairing issues seemed to waste a lot of time and when the temp probes stop working or the gauge drops off it becomes a useless boat anchor instead of a precise tool. I was hoping to get a year or so out of these...three weeks it was. Save your money and buy a higher quality tool.

I love them , they make it alot easier
