Carbon Dioxide Sensing | CO2 Detector | Carbon Dioxide Sensors

Carbon Dioxide (CO 2) is a colourless and odourless gas, vital to life on Earth, as such carbon dioxide sensing is an important practice. Although difficult to detect, our range of carbon dioxide detectors allow carbon dioxide to be strongly absorbed thanks to our non-dispersive infrared technology in our CO 2 detectors.. Carbon dioxide is mostly nontoxic, unless concentrations become elevated.

AIR2COLOR PRO : Renz

CO2. The carbon dioxide (CO₂) content of air is an indicator of air quality. The higher the CO₂ content, the lower the quality and Oxygen content which leads to a decrease in concentration and productivity. Higher CO₂ levels mean a higher aerosol concentration, which can increase the risk of virus infection.

Breath emulator for simulation and modelling of expired ...

Nov 04, 2020 · Background. In this work we describe a breath emulator system, used to simulate temporal characteristics of exhaled carbon dioxide (CO 2) concentration waveform versus time simulating how much CO2 is present at each phase of the human lung respiratory process.The system provides a method for testing capnometers incorporating fast response non-dispersive infrared (NDIR) CO 2 …

Optimization of a Membrane-Based NDIR Sensor for Dissolved ...

The autonomous measurement of dissolved carbon dioxide (CO2) is of great and still increasing importance for addressing many scientific as well as socio-economic questions. Although there is a need for reliable, fast and easy-to-use instrumentation to measure the partial pressure of dissolved CO2 (pCO2) in situ, only few autonomous underwater sensors are available.

(The ratio of unburned hydrogen to water is determined by the ratio of CO to CO2 in the numerator). The Lambda result is a dimensionless value that indicates the balance of air to fuel compared to the stoichometric point, where Lambda = 1.000. As an example, Lambda of 1.010 means there is 1% too much oxygen (1% "lean" of stoichometric, not 1% ...

Infrared investigation of CO2 sorption by amine based ...

CO2 sorption into/desorption from PEI layers was monitored at different CO2 concentrations, temperatures and humidities by in-situ transmission infrared spectroscopy. It was found that the CO2 adsorption takes place in two steps: a fast adsorption at the upper surfaces followed by the slow diffusion of the chemisorbed CO2 in the bulk.
