Model PAS 2000 - Photoelectric Aerosol Sensor (PAS) Brochure

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 has a higher efficiency than any traditional UV lamp. The Excimer lamp can be rapidly switched on and off without a time delay. The offset produced by pre-charged particles can be eliminated by operating the lamp in a chopped mode.The Excimer lamp produces monochromatic radiation with a half bandwidth of 2%. Higher sensitivity instrument with a larger measurement range. Total microprocessor control with internal data acquisition and storage
