Digital Micron Vacuum Gauge 1/4" SAE, Digital Pressure Tester Meter HVAC, Alarm Notice, Temp Compensation, LCD Display, 6 Units

Seems quite accurate and worked flawlessly for me. I recommend.

Will not hold a vacuum. First time it was hooked up and used, it would never hold a vacuum. Checked all hoses and connections and tried repeatedly and it failed every time. Took this gauge back to our shop and ran bench testing in a controlled environment with same results. Maybe it is just this one that is bad but it can't be returned now that it is outside the time period. We do not plan to buy another of this model,ssssssssss

Good meter. Works for mini split install.

Excelente

Really wanted this to work. I hate sending things back. I tested it with different fittings, hoses, etc. to make sure it was really the gauge leaking. All the other parts held vacuum for well over an hour with no loss at all. With this gauge connected the vacuum is lost in under one minute.

Good microns gauge

I bought this as an end of season tool after my field piece came up missing. It shuts off every couple minutes and never seems to get below 1500. My coworkers cps gets to 350 on the same setup, after we gave up on this piece of junk. Should've just spent the money on a real tool. Live and learn.

pure junk , i guess you get what you pay for !!!! and you can't get your money back , they put it in a amazon account that you can't access !!
