While you were sleeping I have been active in booting out some spammers along with the posts they tried to sneak past me

Eth Nat Yirg Idido roasted yesterday. I dropped some off at a friends coffee shop. In a few days he will brew it and tell me what he thinks. We believe my roasts are better than what we buy.

Pascal Gauge
Trying to find a 0-500 pascal gauge. Like the one on the 1kg Mill City.

Check Dwyer 2000-500PA Magnehelic
A few options:


1/2 lb and 1 lb drum, Siemens Sirocco fluidbed, presspot, chemex, cajun biggin brewer from the backwoods of Louisiana
I notice many cannot tolerate high temp
Thanks for the suggestions.
I am want to purchasing one of the Dwyer gauges. My understanding is I want to ready vacuum inside the roast chamber? The gauges recommended does not show a negative sign. Could someone please explain. Thanks
For anyone needing a US source for the gauge reading pascals


jp, why the need to measure vacuum?

My thought is the drum fan is pulling air through the drum. There would be vacuum not pressure?
The reason for hooking up a Dwyer gauge to the drum/plenum/exhaust is to adjust the exhaust blower air flow. The would apply to a machine with a damper or variable speed fan.

For a 1k and under roaster the Dwyer 2000-00 0-0.25” wc should do the job and I have had good luck buying used gauges off Ebay. The easiest way to install is to drill out the plenum and tap in a fitting, tube it to the low side and put a little filter in the high side. They can be flush mounted or face mounted using a home made part from scraps. Once the gauge is installed you can use it to replicate any established air flow setting and figure out some new ones. Very handy inexpensive upgrade mod!
Reading negative pressure on the exhaust duct would be useful but curious why the mil city 1kg is using a range of 0-500 pascals (0-2" H2O) which would be out of optimal range for typical drum roaster exhuast fans and also out of range for LP and natural gas pressures.
