  • Operating Principle of an Oxygen Monitor

    The oxygen concentration in the flue gas of a combustion process such as that of a power plant or a waste incinerator gives a good indication of the efficiency of the combustion process. The parameter is therefore of great interest to optimize fuel economy, but also to control and reduce emissions of air pollutants. An ideal combustion process only results in CO2 and water, but ...

  • Time to change habits, as well as light bulbs?

    November 16, 2010 We are bombarded daily by advertisements selling us soft drinks, pharmaceuticals, cars, insurance, junk food, teeth whitener, diet programs, and on and on. But when was the last time someone tried to sell you on using more electricity? I cannot think of a single commercial that encourages us to plug-in, even though electricity is the chief product of 3,000 utilities in the ...

  • Asbestos monitoring – what monitor should I be using?

    Asbestos is the name given to a group of minerals that occur naturally as masses of strong, flexible fibres that can be separated into thin threads and woven. These fibres are not affected by heat and do not conduct electricity. Asbestos is chemically, relatively stable. For these reasons, asbestos has been widely used in many industries.  These four types are classified as follows:  ...

  • What is the Difference between a PM2.5 Monitor and a PM10 Monitor?

    Ambient air particulate monitoring is of more interest than ever before. The reason is new public awareness of the health effects of small particles suspended in the air, in combination with increased vehicle fleets emitting such particles. “PM” stands for particulate matter. The number (usually 10 or 2.5) indicates the size of the particulates monitored. ...

  • Radiation Monitors and Meters

    Light Description and Applications The light meter is a portable unit designed to measure visible, UV, and near-UV light in the workplace. (The CTC has a UV light meter available through its loan program, ALEP.) The light meter is capable of reading any optical unit of energy or power level if the appropriate detector has been calibrated with the meter. The spectral range of the instrument is ...

  • X-ray slag monitoring

    According to market research published by the Freedonia Group in June 2006, global demand for cement is forecast to ‘grow to 4.7 per cent yearly through 2010’. While demand for Portland cement, which currently accounts for three-quarters of all cement sales worldwide, will be healthy, sales of blended cements are expected to climb at a faster pace. Similarly, the Slag Cement Association reports a ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Why monitor dust in the workplace?

    Almost any place of employment can present a potential threat to health and safety from airborne particulates and aerosols. It is important to note, however, that dust hazards are not necessarily visible to the human eye and that the finest particles can represent the greatest threat because of their ability to travel deepest into the lungs. Effective monitoring is therefore key to the ...

  • The Light at the End of the Tunnel - How to Successfully Operate a UV Disinfection System

    ABSTRACTOver the past ten years, ultraviolet (UV) technology has become a commonly applied method of disinfecting of wastewater effluent. UV disinfection involves passing wastewater effluent through a confined chamber with rows of underwater lamps emitting UV energy. Viruses and bacteria become inactivated upon exposure to dosages of UV energy, thereby disinfecting the wastewater. The UV system ...
