Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is non-dispersive in the fact that no dispersive element ( a prism or diffraction grating as is often present in other spectrometers) is used to separate out (like a monochromator) the broadband light into a narrow spectrum suitable for gas sensing.

Oxygen sensor - Wikipedia

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed.. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ...

3 Ways to Test for CO₂ - wikiHow

Jun 22, 2020· Carbon dioxide extinguishes fires, in high concentrations. You'll simply need to hold a small lit flame inside a test tube that you suspect contains CO 2. If the gas is present, the flame should go out immediately. Combustion (creation of a flame) is the reaction of oxygen with another substance; it is a rapid oxidation of the organic compound ...

NDIR CO2 Sensor | SSU Ocean Instruments Wiki | Fandom

A non-dispersive infrared (NDIR) carbo dioxide (CO2) sensor is commonly used to measure atmospheric CO2 and partial pressure CO2 (pCO2) of seawater. The sensor is spectroscopic. CO2 molecules absorb infrared light. An infrared light is passed through a tube that the gas to be measured. The amount of infrared light absorbed is then measured. Therefore, the absorbance can be used to calculate ...
