The AirSafe PM provides continuous and precise monitoring of dust exposures in indoor ambient air.
The AirSafe PM can be used for indoor workplace exposure monitoring, utilizing the high range and low range sensors to detect and track particulate exposure limits and limit violations.
Health and safety personnel can use the measurement data to provide a safe working environment and report site air quality.

The AirSafe PM is designed to be used indoors only. It can be installed in any room that needs particulate
monitoring as part of exposure and health safety limit monitoring.
The AirSafe PM can be easily mounted to most surfaces and areas, such as:
Install the AirSafe PM as near as possible to air intakes, areas of air movement, and areas of static air/settlement where people work. When positioned near the ventilation and filtration apparatus, the AirSafe PM can be used to monitor the effectiveness of the ventilation and filtration process.
