The atmospheric particulate matter monitor uses beta radiation absorption to measure PM2.5 concentrations. It consists of three main components: the unit, cutter, and sampling system. Users can set parameters for continuous online measurement.
· Large touchscreen with intuitive interface, supporting multitasking.
· Selectable PM2.5 cutter for real-time particle monitoring.
· Mass flow controller with closed-loop control for high precision.
· Dynamic Heating System (DHS) to mitigate humidity effects.
· Up to 2 years of data storage, with report query and USB export.
· Communication via RS485,RS232,and Ethernet.
· Compact, auto-calibrating design with alarm and filter tape method for high sensitivity.
· Low maintenance and operating costs.
