Description
The Met One Instruments ES-405 Simultaneous Particulate Profiler is a high-performance ambient dust monitoring instrument designed for real-time, multi-channel particulate measurement. Using right-angle laser light scatter technology with a high-power 785 nm diode laser, the ES-405 simultaneously measures PM1.0, PM2.5, PM4.0, and PM10 concentrations with excellent resolution down to 0.1 µg/m³. Active volumetric flow control, combined with a stable brushless diaphragm pump and controlled sheath air system, ensures accurate and repeatable data even in challenging environmental conditions. With wide measurement ranges and user-selectable logging intervals, the ES-405 delivers reliable particulate profiling for both short-term events and long-term monitoring programs.
Built for continuous outdoor and industrial operation, the ES-405 features automatic humidity control via an inlet heater, a rugged enclosure, and multiple communication options including RS-232, RS-485, and USB for seamless integration with data loggers, SCADA systems, or remote networks. The intuitive OLED display and menu-driven keypad simplify configuration and on-site operation, while alarm relay outputs enhance safety and compliance monitoring. Certified to MCERTs, CE, and ISO 9001 standards, the ES-405 is ideally suited for applications such as ambient air quality monitoring, industrial hygiene, mining operations, smart city deployments, tunnel and fenceline monitoring, emergency response, and occupational dust assessment, where dependable, real-time particulate data is critical.
