  • What is an `IAQ Profile`?

    The 'IAQ Profile' is a visual presentation of indoor air quality. PPM Technology's range of IAQ Monitors enable continuous monitoring of Indoor Air Quality; this precisely describes changes in concentration levels of selected air quality parameters over a period of time.  The IAQ Profile provides the knowledgebase and database for improving indoor air quality efficiently and ...

  • Fixed multi-parameter gas detection system can ensure industrial facilities are safe from hazardous or toxic gases

    Industrial workplaces are likely to come across one or more hazardous or toxic gases. Combustible gases such as methane are highly dangerous because they can cause large and fatal explosions when ignited. Other problem areas when working in industry are carbon monoxide (which poisons the cardiovascular system), oxygen deficiency, and elevated levels of other gases and pollutants, depending and ...

  • Monitor Volatile Organic Compounds (VOC’s) with PPM Technology’s IAQ Monitor

    Volatile organic compounds (VOC’s) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOC’s is one of numerous sensor options that can be incorporated into PPM Technology’s ...

  • Air‐plant exchange of brominated flame retardants at a rural site: Influencing factor, interspecies difference, and forest scavenging

    Brominated flame retardants (BFRs) in eucalyptus leaves and pine needles from a rural site in southern China were measured to investigate the air‐plant exchange. The mean concentrations of BFRs were higher in pine needles (79.8 ng/g dry weight) than in eucalyptus leaves (74.5 ng/g), whereas an inverse result were found for the leaf surface particles (LSPs), with mean concentrations of 3490 and ...

  • `Green Buildings` can create problems with IAQ

    The recent trend towards energy conservation measures have in some cases led to airtight building construction that can often create problems with Indoor Air Quality (IAQ). Some 'green buildings' (also known as ‘green construction’ and ‘sustainable buildings’) have ignored the issue of IAQ in pursuit of energy saving measures. Ventilation systems are set to minimize the ...

  • Wireless monitoring for a safe indoor environment

    This article discusses the benefits of wireless technology for continously monitoring the indoor environment. In striving for the construction of energy efficient and cost-effective buildings, the imperative issue of the buildings Indoor Air Quality (IAQ) is often overlooked. This can often lead to a unhealthy indoor environment and even to conditions such as Sick Building Syndrome (SBS) or other ...

  • Empirical validation of a new heat stress index

    Thermal stress is a well-recognised health hazard in the workplace. In addition to the health deficits, working in the heat can impact significantly on the productivity of some industries which are located in harsh environments. A long-standing dilemma in OHS has been the specification of what constitutes a safe working environment. The current indices used to evaluate the environment are either ...

  • Closed vessel or open channel UV disinfection systems

    Ultra violet disinfection is now a standard feature in most waste water disinfection systems. UV has also been adopted by the drinking water community, as a barrier against the chlorine tolerant species such as Cryptosporidium and Giardia. The technology is widely favored due to its non- chemical nature, the fact that no subsequent de-chlorination process is required, and its ability to be ...
