Portable handheld device for monitoring particulate matter (PM) concentrations in the air / 2.5 µm and 10 µm particle sizes / Measures air temperature and relative humidity. Designed to aid in indoor air quality (IAQ) assessments, this dust monitor also measures air temperature and relative humidity (RH). The dust monitor can be powered either by the built-in rechargeable battery or the USB port. The USB port also is used to charge the battery.
