Principle of NDIR CO - SENSOR+TEST

Principle of NDIR CO2 sensors The NDIR(Non-Dispersive Infrared) utilizes the phenomenon that a gas The amount of absorbed IR light is proportional to the concentration. For example, H2O has the maximum absorbance at and ㎛, SO2 at ㎛, CO2 at ㎛, NO at ㎛. An IR source at the end of the measurement chamber emits light into

NDIR Gas Sensors - Electrical Optical Components, Inc.

An NDIR gas sensor (nondispersive infrared sensors) is a simple spectroscopic device often used as gas detector. It is called nondispersive because the wavelength which passes through the sampling chamber is not pre-filtered. Instead a narrow bandpass (or NBP) filter is used before the detector. The NDIR sensor is a broadband IR detector using ...

Nichtdispersiver Infrarotsensor – Wikipedia

Ein nichtdispersiver Infrarotsensor oder NDIR-Sensor ist ein spektroskopisches Gerät, das überwiegend als Gassensor eingesetzt wird. Besonders geeignet sind NDIR-Analysatoren zur Bestimmung der Konzentration von Kohlenstoffmonoxid, Kohlenstoffdioxid oder Kohlenwasserstoffen in einem Gas. Ein typisches Anwendungsgebiet ist die Analyse der Abgase von Verbrennungsmotoren.
