  • Model PAS 2000 - Photoelectric Aerosol Sensor (PAS)

    Model PAS 2000 - Photoelectric Aerosol Sensor (PAS)

    Since 1991, EcoChem has pioneered the use of the Photoelectric Aerosol Sensor (PAS) for real-time measurement of Carbon aerosols. Previous versions of the PAS monitor (PAS 1000i, 1000e and 1002i ) are widely used by regulatory, research and industrial organizations. Incorporating customer feedback and state-of-the-art advances in measurement techniques, the PAS 2000 features the following technological advances: Use of an UV Excimer lamp. This lamp...

  • Model PAS 2200CE - Photoelectric Aerosol Sensor (PAS)

    Model PAS 2200CE - Photoelectric Aerosol Sensor (PAS)

    The PAS 2000 works on the following principles: Using an Excimer lamp the aerosol flow is exposed to UV radiation. The Excimer lamp offers a high intensity, narrowband source of UV radiation. The wavelength of the light is chosen such that only the carbon aerosols are ionized, while gas molecules and non-carbon aerosols remain neutral. The carbon aerosol particles emit electrons, which are subsequently removed when an electric field is applied. ...

  • Model DC 2200CE - Diffusion Charger

    Model DC 2200CE - Diffusion Charger

    Detects particulate-matter surface area through diffusion charging. Lightweight, compact and ruggedized construction. Battery powered with onboard data storage. Applications related to personal exposure in various environments (homes, workplace, automobiles, tunnels etc.). Companion product to the PAS 2200CE --- the DC 2200CE measures ALL particulate matter, the PAS 2200CE measures PAH (primarily on carbonaeous matter).
