  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Case Study: Singapore Airlines

    Ellis was contacted after a client had several complaints from employees related to air quality. Ellis conducted exposure monitoring for CO2 and CO, and also took measurements of temperature and relative humidity. Results of the study showed CO2 and CO to be well under the PEL (Permissible Exposure Level) for those two gases. However, elevated temperatures occurring later in the day appears to ...

  • G100 portable CO2 incubator analyser for incubators gas readings

    The Geotech G100, which measures CO2 from 0-20%, is used to demonstrate accurate and repeatable CO2 readings of the atmosphere inside incubators. In just a few seconds an embryologist is able to take a reading from various incubators, all of which will have a different means of sampling the air inside an incubator, without fully opening the inner door and adversely affecting the environment. It ...

  • Thermal Patters Due to Moisture Accumulation within Exterior Walls

    In cold climates, air leakage is accompanied by moisture transport. When migrating through dew point temperatures, a considerable amount of moisture accumulation may occur depending on variables such as the duration of sub-zero exterior temperatures, building pressurization, wind effects and the level of interior relative humidity. Moisture accumulation may result in premature deterioration of ...

  • Analysis of an anomalous case of high air pollution concentration in Turin after a foehn event

    A case of unusually high concentrations of some urban air pollutants (CO, NO, SO2) in Turin (Northwestern Italy) is presented. This episode occurred during the late afternoon of 7 November 1995. This day was characterised by a strong northern foehn event in the morning, which followed the passage of a cold front. The analysis has been carried out by means of data derived from the urban and ...
