        Particle Counter

        The Met One 227 Handheld Airborne Particle Counter features the sensitivity
        of larger instruments and easy handheld operation. Weighing only two
        pounds, the 227 features a 0.3 micron sensitivity (227B) or a 0.5 micron
        sensitivity (227A), and uses reliable laser diode technology.
        The Met One 227 counts two sizes of particles; the second size is userselectable.
        Configure sample times from one second up to 24 hours. To make
        the most of its portability, the 227 features several counting modes for quick
        analysis of cleanroom conditions.
        Concentration mode: Gives a continuously updated approximation
        of the number of particles per liter or cubic foot.
        The approximation is based on a user-selectable
        sample period of one to ten seconds.
        Auto mode: Automatically takes a specified number of samples
        and stops, allowing unattended operation.
        Average mode: Calculates the average, minimum, and maximum
        count after a specified number of samples.
        Beep mode: Sounds a beep each time it counts a specified
        number of particles.
        To protect cleanrooms, the Met One 227 contains an exhaust filter. The
        pump and sensor are turned off when the battery charge drops below a safe
        operating level, maintaining power to preserve data stored in memory.
        Print results to a remote printer or download data to a computer or
        facility monitoring system. Use PortAll Version 2 software with the 227
        to schedule automated data collection of particle counts. Track
        and identify trends to eliminate particle contamination sources.
