  • Using Open Path TDLAS CO2 Sensors for Carbon Capture and Storage Projects

    Public confidence in CCS projects worldwide is not very high. Many believe that CCS is not permanent storage, and at great expense to govermnents who are funding these projects. Effective monitoring and verification programs could go a long way to improve public perception.  Our Spectra-1 open path TDLAS gas sensor has shown very high accuracy in monitoring ambient CO2 levels. Better than ...

  • CO2 vs. VOC Sensors for IAQ - What`s the Difference

    People sometimes ask about the differences between VOC (Volatile Organic Compounds) sensors and CO2 sensors. While both can be used to measure indoor air quality (IAQ), these sensors are not interchangeable. They measure very different things. CO2 sensing technology by IR (infrared) is stable and is not subject to the short-term, random drift found in air quality sensors. Most IR carbon ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Performance of solid-state sensors for continuous, real-time measurement of soil CO2 concentrations

    Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). In ambient CO2 concentration, the GMM222 sensor averaged 427 ± 8.3 µL L–1. Under variable CO2 ...

  • Intellisenc Greenhouse Controllers for control of CO2, Humidity and temperature

    Optimum and accurate CO2 level is important for effective and efficient plant growing. Too much CO2 creates diminishing return on expense and too little fails to utilize your capital investment. Optimum control of all facets of the growing environment results in high productivity at less costs. Plants need to be able to shed moisture to maintain their capacity to draw in nutrients from the soil. ...


  • CO2 Enrichment in Horticulture... A `Good Life´ for all?

    If you’ve ever watched that classic 1970s TV series, ‘The Good Life’, you might have some idea of the work involved in attaining self-sufficiency. As funny and light-hearted as it was, ‘The Good Life’ offered many insights into the unenviable lot of the vegetable gardener. To its credit, the programme was also ...

  • Carbon Dioxide (CO2) Leak in Soda Machines

    Carbon dioxide, also known as CO2, is a very well known gas type but not everyone knows how deadly it is. Most people know it as a gas that humans exhale but commercially, it is manufactured and shipped as a liquefied compressed gas or is used as dry ice in its solid form. A common use of CO2 gas is in soda fountain machines to carbonate soft drinks by pressurizing the CO2 ...

  • AirTest CO2 monitors & the seattle school district case study

    Background Siemens Building Technology provides the building control solutions for the Seattle School District. The school district has been installing CO2 monitors in gyms, auditoriums and some school classrooms as a way to ensure good air quality and a healthy teaching environment. They are also now realizing that there is an energy benefit to CO2 control in that they can control fresh air ...

  • If the fire doesn’t kill you, the CO2 might – carbon dioxide and fire suppression

    Carbon dioxide (CO2) has been used in fire extinguishers and fire suppression systems for more than a hundred years. In high concentrations it dilutes oxygen, thus removing one of the three elements of the combustion triangle (the other two being heat and fuel). It is also cheap, widely available, odourless, colourless, electrically non-conductive, chemically inert and it leaves no residue. It is ...

  • The beverage industry`s incorrect way of monitoring for CO2 leaks

    Carbon Dioxide (CO2) is the primary compressed gas used for beverages at major fast food chains. This gas is also used in restaurants, gas stations, and grocery stores. When CO2 leaks into a confined space or basement, this creates a very unsafe workplace for employees by lowering the breathable oxygen. History seems to repeat itself all too often while dealing with CO2. Due to the CO2 leaks ...

  • If you can’t stand the CO2, get out of the kitchen – Part 2

    In Part 1 we reviewed the many standards, specifications and technical bulletins on commercial kitchen ventilation that have been published since 2000. In Part 2 we investigate four of the more recent ones, with a particular focus on carbon dioxide (CO2) ...

  • CO2 In gyms saves big buck for the Coquitlam school distric case study

    Background The Coquitlam School District has been able to save $10,000 to $15,000 in annual energy costs for each of its schools by installing CO2 based ventilation control in its Gymnasiums and auditoriums. The school district is nestled in the foothills of the Rocky Mountains just outside of Vancouver BC. Besides being blessed with a mild maritime climate (5400 heating degree days, 59 ...

  • If you can`t stand the CO2, get out of the kitchen - part 1

    There are two potentially dangerous types of gas in a commercial kitchen: 1) the flammable ones used for cooking (e.g. methane/natural gas; propane/liquefied petroleum gas); and 2) the noxious, gaseous products of combustion such as carbon monoxide, carbon dioxide and hydrocarbons. It would be good to know how to avoid them. But a search for advice on kitchen ventilation threatens to drown the ...

  • All I Want For Christmas is low CO2 – how Analox do Christmas lights

    It’s the most wonderful time of the year, and the team at Analox have taken a different step into Christmas with this year’s Christmas lights. There are several Christmas trees dotted around the Analox office, and at first glance they look like normal trees with normal decorations. However if you look at them closely, you will see that all the lights flash ...

  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...
