The BAM-1020 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter) using the industry-proven principle of beta ray attenuation.Thousands of BAM-1020 units are currently deployed worldwide, making the unit one of the most successful air monitoring platforms in the world.
Met One Instruments, Inc.’s BAM 1022, Real-Time Portable Beta Attenuation Mass Monitor, continuously measures the mass concentration of ambient particulate matter collected onto glass filter tape with time resolution of one-minute. The BAM 1022 employs an in-line sampling geometry in which the attenuation of beta rays across filter media is measured while particulate matter is sampled simultaneously. This allows ambient sampling to occur for virtually 60 minutes each hour. It also allows for beta ray measurements to be made for virtually the entire hour thereby improving sensitivity and time resolution.
Our E-FRM is a single channel particulate sampler approved as a US-EPA reference method for PM2.5, and alternately configured for either PM10, PM1 and TSP. Configured with an alternate PM2.5 cyclone, the E-FRM may also be operated as a US-EPA designated equivalent method for PM2.5.
Met One Instruments’ E-SEQ-FRM is a Sequential Reference Method sampler that meets the regulatory requirements for PM2.5, PM10 and PM10-2.5 sampling methods. The E-SEQ-FRM accommodates up to sixteen (16) 47-mm diameter filter samples and may be pre-programmed to a flexible, user-defined sampling schedule permitting more than 2 weeks of unattended daily operation.
SASS & SUPER SASS
Met One’s Speciation Samplers are designed to comply and exceed EPA Speciation requirements. Two models provide a choice for compliance monitoring: the SASS is a 5-channel sampling system and the SUPER SASS is an 8-channel, multiple event sampling system. The SASS conforms to original EPA requirements and SUPER SASS adds benefits suggested by state and local authorities.
