A method for the rapid estimation of oxygen and blackdamp in the air of safety-lamp mines
By Briggs H.
The illustrated device uses the principle that the lamp can burn with a smaller inlet passage if the air is rich in O2 and that the size of the inlet can be made a measure of O2 percentage. The applia
