VMV-1 Digital Vacuum Gauge,0-30000 Microns Range, 2% Accuracy, 7/16-20UNF Interface

This micron gauge works perfect, pull a 98.5 micron and hold it with ease! Would recommend for sure!

A few times I've lost hours because the fittings that come with it are useless. The Tee will pull a vacuum, but soon as I start to charge it leaks. The other fitting comes loose very easily. The seller should drop the useless fittings and knock off $10 and just sell the gauge. It's misleading to get extra parts that don't work.

Not very straightforward about how to operate the unit but it reads pretty accurately. Fouls up very easy. Had to clean after every single use.

Very nice instrument! beyond being useful for doing air conditioning on cars.

Easy to use and decent quality

Worked perfect got my Gree flex system down to 95 micron after a nitro pressure test, tested against my older fieldpiece spot on…

Accurately measured pressure, and had no perceived leaks.

I am learning some more about hvac systems from my brother. I picked this up thinking it would be useful. It is very useful in that field of work. We tested for accuracy against his stuff and it was on the money every time. The thing is that I wouldn't know how to use it at all if it weren't for him. The instructions were very poorly written. Some of it didn't make any sense at all. He couldn't even understand what was trying to be explained. To top it off they ripped in half when the box was opened. Very thin newspaper-esque material. It's almost like all I got was a quickstart guide. Once I got the basics down it was pretty easy to use. So, the product is very accurate, easy to use but it helps to have an expert showing you. I hope they revise the instructions and provide a proper manual.

It is a good quality product and easy to use.

I bought this micron gauge and it did work but it failed to calibrate after first use. I contacted the seller and told them the problem they decided to replace my micron gauge. The seller was great to chat with and very accommodating and polite. I received my replacement and tested it today and it works as described. If your sceptical about buying this micron gauge. You need not to be. It was well made and practical. I'm very happy with this product and the seller. Thanks Ken.

Garbage

Nice big easy to read display and displays even atmospheric conditions, microns in my case. This way the process can be followed easily

Compared it to Yellowjacket gauge and was within 20 microns. Excellent for the price.
