Air Contaminant Monitoring Articles

  • How clean is your local air?

    Few people know how clean the air is where they live, work, exercise or where their children go to school. Although air quality can be shown to vary significantly over short distances, air pollution is generally measured using a small number of large, expensive and high quality monitoring stations. The equipment used in these stations is very accurate and complies with measurement standards but ...

  • Facility reduces process downtime – Case Study

    A facilities subcontractor for Boeing required meters to monitor the make-up air mass flow rate into a painting facility. The make-up fans ensure compliance with OSHA and Boeing air quality standards by reducing contamination and airborne particles that result from over-spray. The Boeing standard dictates a minimum airflow of 125 SFPM to the paint booths. Should the airflow drop below this ...
