Alnor Electronic Balometer with APM 150 meter Air Flow Capture Hood with case

I picked this up at an estate. See pictures it powers up but that is the extent of testing.

Please ask questions if needed. I don't have a vent in my apartment to test but I did put the hood over a fan both front and back. I got readings from both sides. 270 front/supply and 119 back/exhaust.
