NomoLine® ISA Gas Analyzers

NomoLine Infrared Sidestream Gas Analyzers (ISA) provide accurate end-tidal carbon dioxide and multi-gas (oxygen, nitrous oxide, and anesthetic gases) measurements in a variety of clinical settings over all patient populations.




50 ml/min sampling rate and small sample cell (15μl) facilitate accurate measurements and crisp waveforms

Calibration-free spectrometer enables fast start up, with full accuracy in less than 10 seconds1
