Nondispersive infrared sensor - Wikipedia
A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas detector.It is nondispersive in the sense of optical dispersion since the infrared energy is allowed to pass through the atmospheric sampling chamber without deformation.
Nondispersive Infrared Detector (NDIR) principle | Cambustion
The Cambustion Fast NDIR uses a unique sampling system, coupled to miniaturised NDIR technology to give millisecond response times. The Cambustion Fast NDIR has two remote Sampling Heads controlled by a Main Control Unit, and is capable of sampling CO & CO 2 simultaneously in two locations. See Applications & Sample Data.
Technical Note 169 Theory And Operation Of NDIR Sensors
THEORY AND OPERATION OF NDIR SENSORS THEORY OF NDIR The MultiRAE IR monitor uses an NDIR (non-dispersive infrared . absorbance) sensor to monitor CO. 2. Most molecules can absorb infrared light, causing them to bend, stretch or twist. The amount of IR light absorbed is proportional to the concentration. The energy
How does an NDIR CO2 Sensor Work? |
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or CO2.

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 Kohlenmonoxid, Kohlendioxid oder Kohlenwasserstoffen in einem Gas. Ein typisches Anwendungsgebiet ist die Analyse der Abgase von Verbrennungsmotoren.
