The most appropriate portable devices to use in the workplace are non-dispersive infrared (NDIR) CO2 monitors. How to use a CO2 monitor. CO2 levels vary within an indoor space. It’s best to place CO2 monitors at head height and away from windows, doors, or air supply openings. Monitors should also be positioned at least 50cm away from people as their exhaled breath contains CO2. If your ...

Non-dispersive infrared (NDIR) gas sensing is one of the most widely used optical gas detection techniques, and there is a wide range of cell designs in commercial manufacture [1]. For some gases, notably carbon dioxide (CO. 2), alternative (non-optical) technologies are unsuitable and therefore CO. 2. detection in low-cost,
Buy the best and latest co2 carbon dioxide ndir on offer the quality co2 carbon dioxide ndir on sale with worldwide free shipping.
NDIR sensors are the most reliable method for detecting carbon dioxide gas. NDIR sensors are based on infrared spectroscopy, the principal that molecules absorb specific light frequencies that are characteristic of their structure. When the frequency of the infrared light is the same as the vibration frequency of a bond, absorption occurs. Infrared light absorption of a particular frequency or ...
