Carbon Dioxide (CO₂) Gas - Gas Detection Australia

Carbon dioxide (CO₂) is a colorless gas with a density about 60% higher than that of dry air. Carbon dioxide is odorless at normally encountered concentrations, however, at high concentrations, it has a sharp and acidic odor. It is a versatile industrial material, used, for example, as an inert gas in welding and fire extinguishers, as a pressurizing gas in air guns and oil recovery, as a chemical feedstock and …

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 light at its characteristic wavelength. The filter …

NDIR CO TECHNOLOGY -

TSI’s IAQ instruments measure carbon dioxide concentration by relying on one of the natural properties of CO 2 molecules: CO 2 molecules absorb light at a specific wavelength of µm. This wavelength is in the infrared (IR) range. High concentrations of CO 2 molecules absorb more light than low concentrations. This technique is called non-dispersive infrared (NDIR) detection. Refer to the …
