  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Green House Gas Flow Monitoring

    This article addresses the challenges and solutions to flow measurement of green house gases in various industry applications.  GHG flow monitoring regulations are discussed and addressed. Last year the EPA implemented new regulations entitled “Mandatory Reporting of Greenhouse Gases.” The new regulations called for certain facilities emitting 25,000 metric tons or more per year ...

  • Monitoring Multiple Gas Hazards in Ice Arenas

    The equipment used in an arena such as an ice re-surfacer, ice edger, floor sweepers, lift trucks and other special equipment are more often powered by fuel than electricity. The exhaust produced by the gas, propane or diesel fuel powered machines emits, into the air, carbon monoxide (CO), nitrogen dioxide (NO2) and particulates. Ammonia (NH3) is commonly used in the ice chiller mechanical room ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • How Accurate is Your Monitor?

    When you consider the many regulations and guidelines that health and safety officers and first responders are faced with, it is amazing they maintain the ability to detect such a wide variety of hazardous pollutants and toxic agents.  There is no lack of regulations governing how to monitor chemical compounds, and the list grows longer all the time.  New standards for portable gas ...

  • Gas Monitor Bump Testing vs Calibration

    We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

  • Electrochemical Sensors for Specific Gas PPM Monitoring

    Echem sensors are able to read a specific gas even when it is mixed in a background of other gases. Echem sensors are typically used to read very low PPM concentrations of toxic gases. The Echem sensor consists of a small cell holding an electrolytic solution. This solution needs a specific gas in order to produce an electrical signal. When the specific gas passes through a permeable membrane and ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...
