Part Number: 770-1620


HD-1620 Multi-parameter Respiratory Monitor Kit, includes monitor, PM2.5 impactor, universal battery charger with plugs, micro USB cable, flow adapter, PM air intake, manual, Dust Comm Pro Software, and certificate of calibration.

Hand held monitor for PM,  U.S. AQI for PM2.5, Temp, RH, Barometric Pressure, and GPS. No calibration accessory is required for this monitor.

The new Environmental Devices Corporation HD-1620 is the only handheld monitor with built-in U.S. AQI for PM2.5! This multi-parameter real-time respiratory air monitor is designed specifically for firefighters, first responders, and occupational hygienists. Identify health concerns in real-time and get the information you need to set up engineering controls for workers such as N95 masking, SCBA respiratory protection, ventilation controls, evacuation, and/or reentry plans to meet your state’s wildfire smoke rule. The HD-1620 is versatile...use it held in your hand, strapped to your hand, clipped to your belt or turn-out gear, or mounted on a tripod. Even with gloves, the large one-button “Go/No Go” provides for easy and rapid deployment. The HD-1620 also complements the EPA PM2.5 and PM10 reference method for outdoor applications to help maintain compliance.
