The Cal/OSHA Wildfire Smoke Monitoring Kit is for employers, health and safety managers, and air quality professionals, who need to monitor the concentration of airborne particles emitted by wildfire smoke – in accordance with Cal/OSHA section 5141.1, Protection from Wildfire Smoke or other similar regulations.

The kit includes the following sensors: particulate matter (PM) sensor (PM2.5 /PM10), and a combined temperature and relative humidity sensor.

Combined with the Series 300 monitor the PM sensor offers the following benefits:

• Active precision active sampling 
• Fast T90 response time 
• Humidity compensation 
• K factor adjustment 

Together, these features allow the PM sensor head to deliver surprisingly accurate real-time data when compared to instruments that cost 20-30 times more. The PM sensor has shown r2 correlations of 0.84 (PM2.5 ) and 0.81 (PM10) in head-to-head field tests with traditional EPA-approved analyzers.

In addition to wildfire smoke, responsible employers may wish to monitor other pollutants of interest. For example, ozone, nitrogen dioxide, carbon monoxide. The Kit can be expanded to measure up to 27 other pollutants that may be putting workers at risk.
