Description:
1950s The Decker Corp. 306-2B Differential Pressure Sensor
From what I can find, this sensor was used with a differential micromanometer in the studies of metals. The one study I found was studying atomic hydrogen at low pressures. It may have been used for other things, but seems like a fairly obscure piece of equipment. It has stickers on top indicating it should only be used with BAC 199634, and, "Use only for special eng'r test set-up. Cert. not good".  It has some wear to case and is missing all but one screw holding case on. It is a very tight fitting top so the missing screws are not an issue. I have photographed the inside as well. It is untested, sold as is. Please see all photos.
The unit measures 4" x 6" x 3-1/2" high.
Weight is 2 lbs 13 oz.
Please see shipping tab for shipping options. Optional local pickup (free) in the Portland OR area available.
