Which vacuum gauge is right?

[valdelocc]

I own the Supernova, I have compared its reading with my Thermal 14571 and they are almost identical.
Lets see what comes next, greenvac? pinkvac?......thats going to create havoc among the zombies

I have only the Yellow Jacket "Deluxe LED" part number 69060. I trust it. Usually anything with a thermocouple vacuum sensor is more reliable/accurate than thermistor vacuum sensors.

valdelocc How old is your DV-40? I had two DV-40's close to when they came out and they were both where a joke compared to my Thermal. I only ever saw reading in the same ballpark when to was a hot summer day.

if i do a small res split

i just put the micron gauge on the high side only, no hose.

then vacuum from the suction side.

this way i trust the micron gauge reading.

as for which one is correct?

who knows?
are they both temperature compensated?

wow
just looked at it

is it for use in the field??????????

I bought it used, lightly used. EBAY, about $170 shipped! Do not be too judgmental, I was using my manifold to evacuate. I did get around 300 millitorr on each unit. Called it good enough, they are my units.

Thanks for taking the time to make the videos and posting! I guess trust no vacuum gauge.
My question though is..... Which vacuum gauge will you continue to use?
I would love to hear what Accutools would say about the video.

I had doubt in micron gauges as well so I did some non-scientific tests. My conclusion.. THey all like to read differently.. Some are way further off then others.. In my experience that Supernova gauge is JUNK..
