What is NDIR? | Oshino Lamps Ltd.

Incandescent lamps with tungsten filament are used for many NDIR CO2 sensors because enough infrared output can be obtained by that type of lamps. Those lamps also have wide wavelength length which covers from the visible light region to the nearinfrared and midinfrared regions. In particular, relatively large infrared output can be obtained at 3 µm to 5 µm wavelength which is required for ...

Basic Principle of NDIR Gas Detection Heimann Sensor

The picture below illustrates the principle using the example of a NDIR CO2 sensor: On the right side we have an IR light source that emits radiation at all wavelengths. The reflector is used to direct as much light as possible in the direction of the thermopile detector which is on the left side. In between there is a tube with IR reflecting walls which is used as measurement path. For CO2 ...

Nondispersive infrared sensor Wikipedia

A nondispersive infrared sensor (or NDIR sensor) is a simple spectroscopic sensor often used as a gas is nondispersive 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.

MHZ16 NDIR CO2 Sensor with I2C/UART Interface Board ...

20110804· A BMP measures the bound CO2, which is really bicarb. ABG''s measure unbound CO2 as well as bicarb. The BMP measure of bicarb is quite useful. There have been a handful of times I''ve drawn a BMP on someone and noted it was high and assumed some acidosis, and when I drew an ABG I was spot on. You can also look at it for trends in your CO2 retainer populations (COPD, PF, sarcoidosis). …
