Absolutely bogus information here. The BlueVac Pro is by far the best Micron guage on the market. I’ve owned several of the units reviewed here and the Fieldpiece SMAN is so bad it shouldn’t even be on the list. Complete misinformation!
Thanks Richard, I will check the product again.
Is your list from 10-1 meaning number one the best or the worst?
All of them are the best.
I thought these were the reviews for 10 best micron gauges.
4. BELEY Refrigeration Digital HVAC System Manifold Gauge is not a micron gauge.
