* a Fisher brand precision movement instrument made in West Germany
* fully functional, as well as decorative and collectable
* indicates near term weather conditions from atmospheric pressure changes; with instruction booklet
* with a flanged bezel of polished brass in a fine wooden 4 in. dia. case having a ship's wheel motif
* with a 2.5 in. dia. dial with open movement and a scale from 26 to 31 in. of Mercury (inHg), finely graduated to .1 inHg. and to .05 inHg.
* can be hung on a wall, or can be free standing with the rear removable wire-like support
Non-essential technical info., that may be of interest:
* with a black index hand that points to the current pressure, and a brass pointer hand that can be manually set to, e.g., standard pressure, or the current pressure - so as to see later pressure changes
* the dial indicates 'stormy', 'rain', 'change', 'fair' and 'very dry' weather conditions as pressure rises from about 28 to 31 inHg
* normal/standard pressure is about 30 inHg (or 14.7 psi), between 'change' and 'fair'
* the barometer is still as calibrated to the factory altitude of 1312 ft. above sea level, and can be used as is for just pressure changes
* or, it can be recalibrated to a local altitude by setting the black hand to the local online atmospheric pressure in inHg, using the rear adjustment screw
(online pressures not in inHg can be converted by multiplying by the appropriate factor as follows: .2953 inHg/kPa; 29.53 inHg/bar; .02953 inHg/mbar; .03937 inHg/mmHg; 2.035 inHg/psi)
