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.

basic information
The HD-1620 is a multiparameter handheld monitor that measures the mass concentrations of PM-TSP, PM10, PM5.0, PM4.0, PM2.5, and PM1.0 in real time, and also supports particle count at selected particle sizes. It simultaneously records temperature, humidity, atmospheric pressure, and GPS, and displays the US EPA AQI for PM2.5 in color. The screen features high-brightness color and allows switching between View1 (numerical display) and View2 (graph display). It is equipped with statistical functions such as STEL, Ceiling, TWA, Min/Max, and allows for alarm settings. Data is stored in internal memory and can be output as CSV via software. The optical chamber can be cleaned by the user, and filter replacement is easy. The sensor has a lifespan of 10 years and automatically notifies the maintenance period. It is powered by a rechargeable battery for long-term operation and supports various installation methods such as hand strap, belt, and tripod. It is designed with a robust structure suitable for firefighting, industrial hygiene, and environmental measurement, and includes a "Go/No Go" button to assist with quick decision-making in the field.
