Met One E-Bam Mass Monitor PM 10 $175  $500 $1,500

The Met One E-BAM is a portable real-time beta gauge traceable to US-EPA requirements for automated PM 2.5 and PM 10 measurement. Built to satisfy users, regulators and those from the health community the Met One E-BAM provides truly accurate, precise, real-time measurement of fine particulate matter automatically. In addition, it is rugged, portable battery operated, deployable in 15 minutes.

E-BAM automates particulate measurement by continuously sampling and reporting particulate concentration, data is updated every second and data records updated every minute. E-BAM eliminates the old process of filter collection and manual filter weighing, and eliminates the need for more expensive, high maintenance instruments. Today, with the adaptation of Beta Attenuation to ambient monitoring this process became simple streamlined and inexpensive.
