JB Industries DV-22N Digital Vacuum Gauge

Not sure about the other low star reviews. But I learned that micron vacuuming is quite exacting. To do it right you'll also need the correct hose (all metal) and a closed system valve core remover tool with a side port that will prevent the tiny leak upon removal of a "standard" hose disconnection. The price is good, but the 2 button interface takes some practice to get the feel of.

Easily operated. The auto cal is sometimes disconcerting, but better than manual. Would be nice if it had included a plug to seal off sensor when not in use. Operates as advertised.

Couldn’t ask for better customer service. The product was everything that I wanted and more. I used one just like this for years until it finally broke. I’m glad I found another one

I bought JB digital vacuum gauge from Amazon on July 17 2017. I used it I think 3 times. At this point every time I turn it on the display shows 1 micron then jumps to 336 microns and back to 1 then 366 then repeat. Before I bought JB vacuum gauge I bought microbluevac digital vacuum gauge and it worked just over a month then after that the screen displays H1-P when turns on. I personally lost trust on any digital vacuum gauge.

I gave this gauge five stars. Delivered quickly, and very easy to setup. The fitting is a standard refrigeration fitting , so with a couple of small fittings I was able to read vacuum on some industrial vacuum pumps. Starts up ready to go.

Works as discribed

Ordered this device but hadn't used it till now, it will not read. Called JB Industries they will not warranty because I didn't buy from them. Amazon return policy expired $150.00 down the drain.

Accurate meter
