I. Overview
The HDL-FC-100 handheld laser inhalable dust continuous detector (hereinafter referred to as the dust detector) is primarily used for detecting the concentration of dust particulate matter (PM2.5, PM10, TSP, temperature, humidity) and providing an over-limit alarm in industrial and mining enterprises. This instrument sucks in air containing dust particles from large public indoor spaces, industrial and mining enterprises, factory workshops, or production areas, analyzes it using a high-precision laser dust detection sensor, and displays the dust concentration value in that space on the instrument's display screen.
The HDL-FC-100 handheld laser inhalable dust continuous detector utilizes the advanced light scattering principle, employing a semiconductor laser as the measuring light source to conduct highly sensitive non-contact measurements of dust in the air. The entire testing process is managed and controlled by a single-chip microprocessor, and a high-resolution, large-screen, high-brightness liquid crystal display with full Chinese display is adopted.
