03/06/2019· Carbon monoxide (CO) is one of the toxic air pollution produced in incomplete combustion of carbon-containing fuels. At a certain threshold of concentration, this gas can harm the environments and affect the human health. Unfortunately, it cannot be detected by humans. In this study, CO gas detection has been designed and constructed using the principle of Non-Dispersive Infrared (NDIR). …
01/05/2017· Carbon monoxide was selected because it has low spectral absorption compared to other emission gases as well as low concentration which needs an analyzer with a high sensitivity. 2. Experimental Apparatus. An NDIR analyzer for CO gas (Serinus 30, Ecotech, Australia; analyzer 1) and another NDIR analyzer for CO gas (GP-300, Kentek Ltd., Republic of Korea; analyzer …
Carbon monoxide (CO) is a particularly dangerous toxic gas, not only because it has no colour, no taste and no odour but because it is common in populated areas as a result of the burning of fossil fuels in vehicles and heating systems. Despite advances in detection, CO, or ‘the silent killer’ as it is often referred to, is still responsible for tens of thousands of deaths each year. CO ...
25/04/2020· The detection of the concentration of carbon monoxide in air in the flow‐through cuvette of the NDIR sensor occurs at 4700 nm, the maximum absorption of CO. Measurement is carried out by comparison of the signals of a concentration‐dependent measurement cuvette and the signal of the sealed reference cuvette, which is filled with a constant CO concentration. Depending on the …

NDIR Gas Measurement Principle. To measure the gas concentration with precision, you need two thermopile sensors and an infrared light source. One sensor serves as reference to monitor the variation of IR source output due to source aging, power variations, etc.. The other sensor is equipped with a gas-specific narrow band optical filter.

January 05, 2021. NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of ...
Carbon Monoxide. Bespoke carbon monoxide monitors using NDIR. Carbon monoxide is a colourless, odourless, and tasteless gas that is toxic to animals including humans. In high concentrations, such as used in heat treatment furnaces, it can be measured using NDIR. Our recent article on carbon monoxide detection gives an overview and outlines why ...
The NDIR sensor system for detection of carbon monoxide is shown in figure 6. For calibration purposes, the CO 7701 model produced by AZ Instrument is used to determine the concentration of gas samples. The clean air coming out of the silica gel filter is transferred to the sensor chamber in a few minutes to get the baseline value [11,12]. All experiments were carried out in the laboratory at ...
