  • 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 ...

  • What is the Difference between a gas analyser and a gas monitor?

    Technically, there does not have to be any difference at all. However, semantically, “analysis” might suggest something more scientific with higher precision and better performance than a simple “monitor” which possibly suggests a more indicative output where precision is of less importance. With that said, the two words “analyser” and “monitor” are ...

  • The Basics of Evapotranspiration

    Evapotranspiration (ET) represents the loss of water from the Earth’s surface from the combination of direct evaporation and plant transpiration. ET is usually expressed as a rate such as inches per day. Knowledge of ET is important for irrigation scheduling but it is also an important factor for other land use applications such as septic tank drain fields, watershed level budgeting, and ...

  • Air Quality Monitoring

    Why monitor air quality? Well, to monitor is to know. Everything else is just more or less qualified guesses. International, national and local air quality targets and limits are also tied to monitoring results. What is Air Quality? How is air quality ...

  • 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 ...

  • NILU monitoring air quality for Statoil

    A programme to monitor the environment around the Snøhvit-development in Finnmark county in Northern Norway has been established by Statoil. Norwegian Institute for Air Research (NILU) will be monitoring air quality and precipitation quality before and after the large ...

  • Selecting the Right Air Quality Monitor

    There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • Marine Monitoring of Emissions of Air Pollutants

    Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships, a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution. ...

  • Real-time air emissions monitoring

    Due to increasingly rigorous requirements for regulatory and permit compliance, organizations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

  • Advanced monitoring method for air environment

    The Ogawa Passive Sampler is one of the only known methods of passive simultaneous monitoring of more than two components in the air. The first advantage of Ogawa Sampler is to have two chambers with the same configuration where one can place two different kinds of collection filter pads. In the case of simultaneous collection of NO and NO2, The  O2 collection filter foated with triethanolamine ...

  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Air Pressure Monitoring for a Chemical Fume Hood

    CAS DataLoggers recently provided the pressure and temperature datalogging solution to a manufacturer using a chemical fume hood to protect workers by containing vapors, dusts, gases, and fumes, and then expelling them as air flowed into the hood from the front (open) side of the cabinet and then out via the ducted hood exhaust system. Designed for 2 operators, the fume hood had a Fiberglas ...

  • Multi-Stage Air Quality Monitoring in the Workplace

    CAS DataLoggers recently supplied the environmental datalogging solution for a factory with a small series of office rooms experiencing serious air quality issues. Employees reported headaches during the work day, indicating a possible lack of adequate ventilation. These workspaces were located next to the busy factory floor which caused an incidental ...

  • Status of black carbon monitoring in ambient air in Europe

    Black carbon (BC) is increasingly discussed in science and environmental policy areas as an example of an air pollutant that affects both human health and contributes to climate change (e.g. WHO, 2012; UNEP/WMO, 2011; Bond et al., 2013; IPCC, 2013). In order to be able to make comparable measurements of BC in ambient air and to relate BC monitoring to health impacts and climate change it is ...
