SE-edl software for SE400


Your finger on the pulse

Every breath. Total usage.

The SE-EDL program is a data-logging program that measures every breath taken while wearing the SE400 respirator in real time, at a frequency of 50 Hz. The amount and detail of information gathered gives great scope to further studies in breathing physiology, respirator performance, physical work, and breathing patterns, as well as a wealth of statistical information.
