Title

Biram’s air meter and Portable air meters

Description

Each of the two models of air meter mentioned in the title appear one either side of the leaflet.
Biram’s air meter begins with a brief paragraph, explaining that its distinguishing feature is an indicating dial in the same plane as the rotating vanes so that it can be read when the user holds the meter at arm’s length upwind.
The portable air meter’s introductory paragraph recommends that this instrument is ideal for such work as ventilation engineering, being very easy to set up and use.
Each type of instrument then sets out its information under these headings:-
Principle of operation;
Construction;
General specification;
Catalogue references
