Mesure des expositions aux poussières
L’AirSafe PM permet une surveillance continue et précise de l’exposition aux poussières dans l’air ambiant intérieur : salles de contrôle, zones de stockage, chaufferies, postes de travail, installations
Adapté aux mesures à haute et basse gamme, l’AirSafe PM peut être utilisé pour la surveillance de l’exposition à la poussière sur le lieu de travail afin de détecter et de suivre les limites d’exposition aux particules et les dépassements de seuils.
Les services HSE de votre site peuvent utiliser les données de mesure pour suivre la qualité de l’air sur le site et mettre en place les mesures requises pour assurer un environnement de travail sûr.

monitoring as part of exposure and health safety limit monitoring or for fine process leak detection.
The AirSafe PM can be easily mounted to most surfaces and areas, such as:
- Process areas
- Storage rooms
- Laboratories
- Breakrooms
- Changing rooms
- Office areas
- Other footfall areas of health and safety exposure concern
- Areas of air quality monitoring requirements
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.
When a process need to be monitored to detect minor dust leak, the sensor should be installed in the vicinity of possible leakage.
