PMD 371
PMD 371 is a small, light, and battery-powered particle counter with seven channels for outputs the number of 0.3µm, 0.5µm, 0.7µm, 1.0µm, 2.5µm, 5.0µm, 10.0µm particles, with five channels for simultaneous detection of PM1.0, PM2.5, PM4.0, PM10, and TSP (Total Suspended Particles)mass concentrations.
With a large display screen and seven buttons for operation, the monitor is simple and e cient, suitable for fast detection in multiple scenarios. The internal high-performance
lithium battery allows the monitor to run continuously for 8 hours. PMD 371 also has a built-in 32GB large-capacity storage and supports two communication modes: USB and
RS-485. The detected data can be viewed directly on the screen or exported through the USB port for analysis.
