A multi-parameter real-time monitor that can assess dust exposure "on the spot."
The HD-1620 is a multiparameter handheld real-time respiratory area monitor designed for firefighters, first responders, and industrial hygiene professionals. It offers flexible operation with options for handheld use, hand strap, belt mounting, and tripod installation, and features a large "Go/No Go" button for rapid deployment in the field. It simultaneously displays and records measurements of mass concentrations for PM-TSP, PM10, PM5.0, PM4.0, PM2.5, and PM1.0, as well as particle count at selected particle sizes, temperature, humidity, atmospheric pressure, and GPS. The large color display is highly visible and presents the US EPA AQI for PM2.5 in color-coded format. It also supports real-time graphs, STEL and Ceiling alarms, TWA, and Min/Max statistical displays, with data viewable via software or exportable as CSV. Users are encouraged to perform optical cleaning and filter replacement themselves, with automatic notifications for maintenance timing. The sensor has a lifespan of 10 years, enabling immediate assessment of health risks on-site and assisting in safety management for selecting N95 and SCBA, ventilation measures, and evacuation/re-entry decisions.
