You are looking at a German Spring Force Aspiration Psychrometer. This is used as a service measuring instrument. In 1818, a German inventor, Ernst Ferdinand August (1795-1870), patented the term “psychrometer”, deriving from the Greek language meaning “cold measure”. The psychrometer is a hygrometric instrument based on the principle that dry air enhances evaporation, opposed to wet air, which hinders it
On this item you will see the aspirator, central tube, bend, thermometer, wind wheel, back-pressure spring, plummet with control fields, glass bulb, suction air of thermometer and the control device, air outlet, and the port before control field. On top of the psychrometer you will see the words VEB EAW Elektronik Dresden, Typ 11 and Bj 7190 GDR. The instrument is placed inside a plastic covering then put in a wooden box for protection. You will also get a key and all the papers that were in the box!
This would be a great piece to add to your nautical collection!

Big Ship Salvage scours the world for nautical antique lights, décor and other items related to the Nautical Life. Brass, copper, stainless steel and sometimes aluminum materials are used to make-up the vintage lights that we find. We soda-blast the old paint off, remove the old wiring and polish before they arrive in our warehouse. Then, we rewire with UL listed bulb sockets and wiring harnesses and get ready for purchase. They are now ready to warm your home, business or restaurant with that nautical feeling we all desire.
