The Met One Instruments BT-645 portable dust monitor is designed to continuously measure and record particulate information for indoor workplaces and public spaces. The BT-645 laser optical sensor is used to detect and measure particle concentrations down to 100 milligrams per cubic meter. The continuous flow optical sensor is combined with purge air to ensure accurate measurements in adverse environments. The internal data logger will store over 11,000 samples. Sample history events can be viewed on the display or downloaded to a computer using Comet software. The BT-645 internal battery provides over 10 hours of continuous operation. Battery recharge time is approximately 2.5 hours. The standard unit is supplied with a TSP input. Optional sampling inputs are available for PM1, PM2.5 and PM10. Key points: Four mass ranges (PM1, PM2.5, PM10 and TSP) Robust design Real-time monitoring Example of history Low cost with data logging Air purge system
