Passive air sampling is another way to test an environment for contaminants such as hazardous gases, vapors and airborne particles. Passive samplers are easy to use, as they don’t require electricity or include any moving parts. Here at Premier Safety, we supply a variety of passive air sampling systems, including organic vapor monitors, formaldehyde monitors, ethylene oxide monitors and more. Because the monitoring systems, or diffusers, collect samples over time, they can detect chemicals at low concentrations — allowing you to catch problems before they arise.
