DATA SHEET MET ONE 2400/2408 Portable Airborne Particle Counter Features • Long Life Laser™ technology for superior performance • 0.3 µm (2400) or 0.5 µm (2408) at 1.0 CFM • Up to 6 particle size channels; sequential sampling capability • ISO 14644-1 calculations on all sizes—simultaneously • Memory for 400 count cycles of data—long life laser technology Applications • Monitor and verify cleanrooms • Test filters in place • Track down particle sources • Multi-point monitoring of LAF cabinets, cleanroom laundries, HVAC systems, food and beverage packaging, hospital pharmacies and surgery, aerospace assembly, medical device assembly Flexibility and reliability for sequential sampling The bright LED display makes reading data easy. The display shows particle counts in either cumulative or differential modes, as well as the values from the optional probes for humidity, temperature and air velocity. If your task includes scanning filters, the MET ONE 2400 and 2408 can be ordered with a filter-scanning fan-shaped probe that makes this task go more quickly and accurately. The electronic version provides an audible and visual signal at the probe to help detect filter leaks. For a fixed system, the MET ONE 2400 or 2408 can be coupled with the MET ONE 2432 manifold, allowing sequential sampling of up to 32 sample points. This combination can be an independent system or part of a computer-based FMS system. The MET ONE 2400 and 2408 offer reliability, versatility and ease-of-operation in a lightweight package. If your requirements are limited to detection of 0.5 µm and larger particles—choose the MET ONE 2408. If you need sensitivity at 0.3 µm, then choose the MET ONE 2400. Both will give you solid performance in a quiet and lightweight package. In addition to laser reliability and flexibility, MET ONE 2400 and 2408 are easy-to-operate. Breakthrough Long Life Laser technology extends the average service life of the instrumentation’s laser to more than ten years for either model. A quiet, carbon-free pump provides steady vacuum power at 1.0 CFM (28.3 LPM). The built-in printer allows for immediate or delayed printing of results. Using Particle Vision® PortAll™ software, data can be downloaded at the operator’s convenience from the 400-record buffer and displayed as a graph or a table in the built-in spreadsheet.
