A dumpster from a hospital netted me 6 or 7 blood presser gauges wile the case is AL it's the measurement glass tube that is of interest . The Mercury is stored in a area of device and as pressure is put to hose Mercury travails up . the measurement glass tube looks to be 18 inches long and as thick as a pencil.
Wile this devices is great to measure pressure, I can't think of any way to use for my needs .
As seen by someone selling Mercury on e bay , is Mercury valuable, I have a dozen or so Mercury switches from thermostats but this item has me curious
