Passive-Desi Tube
    The TWA measurement system consists of Gastec Dosi-Tubes
    and the No.710 Tube Holder. Direct reading Passive Dosimeter-Tubes
    are specially designed tubes for measuring time-weighted average gas concentrations.
    They can be attached to a pocket or collar using the No.710 Tube Holder
    to measure the breathing zone of people in a work place
    for a prolonged period of time (1 to 10 hours) to determine personal
    exposure values.
    With this system day-to-day gas concentration fluctuation
    or gas concentration distribution in the workplace can be easily obtained.
