Inficon Pilot Plus, Digital Vacuum Micron Gauge with 1/4" Male Refrigerant Flare Connection, 710-202-G1

Needed a gauge for DIY mini-split install, and this did the trick just fine.

Had a CPS micron gauge work great till I got it wet my fault. I thought I would buy a better quality I had IFICON leak detector for 10 years before I wore it out. Yes I am a professional HVAC person 40 plus years in the business. First job I used the ificon micron gauge on would only read calibrate. I have field piece digital gauges micron gauge on it would read 600 microns not real precise but a good back up. So I thought maybe my field piece was gone , vacuum pump bad or hoses weeping So got my black yellow jacket hoses and a new 2 stage 7.5 vacuum pump ( my back up) set it up in my garage just gauge one hose and pump still only read calibrate, change screen put new battery in no change. One reason I went to so much trouble because IFICON is such a good product. Maybe this gauge is not suited for field work just lab work. Sent it back still waiting

Compact, gets the job done

Works as described.

Highly reliable, repeatable results. Made in USA. The only trivial issue would be the 9v battery wired connection can be difficult to connect to the battery. It would be better if the battery just slipped into the case and that was it. I would buy more if needed.

they can not be calibrated, I bought 4 and 2 failed calibration and 1 stopped working after the first time. reads 1 micron all the time. and to late to send it back. what a waste of money, buy ritchie instead.Update............. only 1 out of all I bought, is still working. honestly, these things are not worth your money. Buy anything else. Seriously ! If I could give it less then one star I would.

Probably should have returned it under warranty, but not worth the times and hassle.
