YYT265 Inhalation Gas Carbon Dioxide Content Detector
This product is used to test the dead chamber of positive pressure air respirator. It is designed and manufactured according to the standard ga124 and gb2890. The test device mainly includes: test head mold, artificial simulation respirator, connecting pipe, flowmeter, CO2 gas analyzer and control system. The test principle is to determine the CO2 content in the inhaled gas. Applicable standards: ga124-2013 positive pressure air breathing apparatus for fire protection, article 6.13.3 determination of carbon dioxide content in inhaled gas; gb2890-2009 breathing protection self-priming filter gas mask, chapter 6.7 dead chamber test of face mask; GB 21976.7-2012 escape and refuge equipment for building fire Part 7: Test of filtered self rescue breathing apparatus for fire fighting;
Dead space: the volume of gas re inhaled in the previous exhalation, the test result should not be greater than 1%;
