Instant Results When Time Is Critical. 

Carbon monoxide is colorless, odorless and difficult to detect. The new microdot® CO Breath Analyzer is FDA approved for CO poisoning detection providing a rapid assessment of Carbon Monoxide poisoning for Emergency Services and First Responders. microdot® CO Breath Analyzer will give instant breath results in %COHb and PPM. Both measurements are backed up with color indicator lights for immediate visual display. microdot® CO Breath Analyzer has been designed to enable emergency service responders to carry out a simple breath test to establish carbon monoxide levels in a subject’s blood. When dealing with CO, time is critical. In the blood stream, Carbon Monoxide has an affinity with hemoglobin some 200 times greater than Oxygen. When this happens, the blood is no longer able to carry oxygen. This lack of oxygen causes cells and tissue to degrade or die.
