  • AirTest CO2 Monitors & The Seattle School District
    Siemens Building Technology provides the building control solutions for the Seattle School District. The school district has been installing CO2 monitors in gyms, auditoriums and some school classrooms as a way to ensure good air quality and a healthy teaching environment. They are also now
  • Application of Fast Response Dual-Colour Pyroelectric Detectors with Integrated Op Amp in a Low Power NDIR Gas Monitor (.pdf)
    Monitoring the concentration of carbon dioxide (CO2) is increasingly being used as a surrogate for determining indoor air quality (IAQ) and to decrease energy consumption of enclosed office spaces. Currently available CO2 sensors for these applications, however, are not being used in private homes
  • Passive Sensing of Driver Intoxication (.pdf)
    A sensor that passively monitors the driver for intoxication has been demonstrated. The driver's blood alcohol concentration (BAC) is obtained by sensing alcohol and CO2 in air drawn from the vehicle cabin. With a legally drunk driver, the steady state alcohol concentration can be as low as 0.3 ppm
  • Wireless Monitoring and Alarming System for IVF Incubators
    . This complex setup required an automatic system to monitor and alarm temperature, humidity and CO2 in real time to alert staff of unsafe levels and help prevent any losses.
  • Operational Guidelines for Highly Reactive Toxic Gas Measurement
    HF, HCl, and CO2 are three of the most challenging gases to monitor for toxicity exposure. This is. in part because the toxic exposure levels are quite low (< 10 ppm), and secondly due to the reactive. nature of these gases. This combination presents a difficult challenge not observed
  • Measurement of Freon 14 (CF4) in an Aluminium Production Plant
    be monitored throughout the changes. Before the emission gas is analyzed in the monitor, it is pre-treated to remove some of the interferents. HF, SO2 and CO2 are removed by passing the emission gas through bottles containing 1N sodium hydroxide. Water vapour is reduced by passing the gas through
  • Direct In Situ Zirconia Oxygen Analyzer (.pdf)
    and pulp, food, or textiles, as well as incinerators and medium/small boilers. It can help conserve energy in these industries. The ZR402G also contributes to preservation of the earth's environment in preventing global warming and air pollution by controlling complete combustion to reduce CO2, SOx
  • Application of BlueSens (R) Gas Analyzers in a Cell Culture Process
    Comparison of O2/CO2 analyzer by BlueSens with a mass spectrometer. Survey by Mathias Aehle, Center for Bioprocess Engineering, Martin-Luther-University Halle-Wittenberg, Halle (Saale), Germany. If you are planning to purchase an old fashioned mass-spec to monitor you bioprocesses you might want
