* Approximate Size (WHD): 28.4 x 11.4 x 23.5 cm
Anemotherm is a trademark of Anemostat Products Division, Scranton, Pennsylvania, Dynamic Corporation of America. This type of air meter was used by the Astronauts on the NASA Apollo Space Missions! It dates to the 1950s/60s.
It operates from nine 'D' sized batteries, which are not included due to most couriers having now banned shipping anything containing batteries.
In working condition, however I can't guarantee its accuracy as it hasn't been calibrated for many a year.
The metal transit case and red leather carrying strap are scuffed and worn but intact.
Serial popular Number: 12467
Originally owned by: Aspiration Ltd, London, UK
The patents date from the 1940s-1950s.
