New to me.
Yes, they work well. More accurate/dependable than any digital/electronic vacuum indicater you can buy. JMHO
Here Looks Interesting enough. I would like to see one in action. How exactly does it work.
I say it still looks like a bong. :D
OH........HMMMM the more messed up you get the better the vac you pulled.
Its a wet bulb vacuum indicator. There is a thermometer in it that is wetted with vacinol. The lower the vacuum, the lower the bioling/evaporation point. 38F is around 6000 microns. There is a chart that relates the temp vs vacuum.
Good Exp Thanks
anyone know the price on this item ? looks interesting .
could possibly retire my mercury absolute monometer.
Never seen 'em at the supply house...............Quote:

Would like to take a closer look.
Got to email the guy to get delivery and price info. None of the supply houses sell this. Its been around forever, long before electronic ones. All the York books show it in their evacuation procedures.

Please read my post on vacuum readings thread. I've seen this device in action on a large system, estimated cost is about $150.00, not bad when when you consider the cost of an accurate electronic meter.-GEO
