Capnograph CO2 TEST 2000 IR is designed for continuous non-invasive monitoring of CO2 capacity in air exhaled by a person. The device analyses the sample in the side stream, taken from the main exhalation track. Sucked-up by an analyzer air is transferred through a dryer device to the quick analyzer, operating on a infrared absorption method. The analyzer operates "breath-by-breath" method and gives the following carbon dioxide concentration values: final exhalation and average for whole exhalation.
