ASA Carbon Monoxide Detector
ASA Carvon Monoxide Detector
This is a great product for anyone who works with equipment indoors. It is great to let t crew know if they are in an area of high levels of carbon monoxide and allow for them to get to fresh air. I highly recommend it for anyone working with equipment in an enclosed area.
Gotta have one in the plane and Pilot Mall sells these for a dollar or so cheaper that everyone else!
