TELEDYNE ADVANCED POLLUTION INSTRUMENTATION A Teledyne Technologies Company TELEDYNE ADVANCED POLLUTION INSTRUMENTATION READY ULTRAFINE PARTICLE MONITOR - MODEL 651 WATER FILL Model 651 Ultrafine Particle Monitor The Teledyne API Model 651 is the first network-ready total ultrafine particle monitor for use in routine ambient air monitoring applications. The Model 651 instrument is designed to measure a wide spectrum of ultrafine particles found in ambient air, including the smallest ones found close to emissions sources. The instrument uses a patented water-based condensation particle counting technique which provides extremely small particle detection limits, as well as real-time continuous data availability. The particles enter the instrument through a standard inlet and are passed through a condenser tube where they are grown to a uniform size. Immediately following the condenser tube, the particles are focused through an inlet nozzle and individually passed through an optical chamber where they are counted. The user interface is simple and easy to use. Through the color touch screen interface, you can view the current operating parameters, real-time graphs, and obtain diagnostic information. Key operating parameters within the instrument are continuously logged to ensure accurate operation. This diagnostic information is stored in the internal data buffer. The instrument can be accessed through connection to a digital datalogging system or using the supplied remote communications software package installed on a personal computer. Routine maintenance is straight-forward and is typically performed on a 30 day interval. The primary maintenance items include refilling the water supply bottle, replacing the supply wick, and cleaning the mesh inlet screen.
