Handheld real-time breathing air monitor

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.

Detailed information

• 

  【Example of Use at a Fire Scene】 A firefighter wearing fireproof clothing and a gas mask working in smoke. The HD-1620 is a portable air quality monitor that measures dust concentration in the breathing zone in real time, assisting in safe evacuation decisions and the selection of protective equipment.

• 

  【Measurement Screen (View 2 Display)】 The high-brightness color screen of the HD-1620 displays a graph of the temporal changes in PM concentration. You can visually confirm STEL/Ceiling alarms and statistical values, allowing for immediate understanding of dust concentration trends on-site.
