  • NDIR Gas Sensor Modules - Electrical Optical Components, Inc.

    The Functional Principle of Smartgas Sensors & ModulesGas Sensors For The Process Measuring TechnologyGas Sensors For Ambient Air MonitoringThe IR principle uses the individual absorption spectrum of the gas being measured. The exact gas concentration is determined through precise quantitative analysis of this spectrum. Because of this, their gas sensors function very selectively and are virtually unaffected by other environmental factors or gases. The functional principle of our gas sensors: long-term stability and performance thanks to NDIR technology from smartGAS As all measured gases absorb in varying spectral ranges, a kind of “fingerprint” arises that allows very selective characterization without cross-sensitivities. Gas sensors from smartGAS possess an integrated electronic evaluation system that displays a simple to use concentration signal to you as the user and reliably compensates for all drift and temperature influences.
