Ambient Particulate Monitors and Samplers

Met One Instruments, Inc. Ambient Particulate Monitors and Samplers

Sample, record, and monitor the ambient environment

Met One Instruments, Inc. offers comprehensive lines of ambient particulate monitors and samplers. Ambient particulate monitors sample, measure and log the concentration of ambient particulate matter (TSP, PM10, PM2.5 or PM10-2.5). Ambient particulate samplers, on the other hand, sample and deposit ambient particulate matter onto pre-weighed filters for later gravimetric or speciation analysis in a laboratory (TSP, PM10, PM2.5 or PM10-2.5). 

Our beta attenuation mass monitors, “BAMs”, are used throughout the world for applications requiring the highest possible accuracy and precision. The BAM-1020 is the flagship of the BAM line with certifications in the United States, Europe, China, Korea, and Taiwan. More than 15,000 BAM-1020 monitors have been sold to date. The BAMs offered by Met One Instruments, Inc. are:

  • BAM-1020 Beta Attenuation Mass Monitor
  • BAM-1022 Continuous Beta Attenuation Mass Monitor
  • E-BAM Portable Beta Attenuation Mass Monitor
  • E-BAM PLUS Portable Beta Attenuation Mass Monitor

Met One Instruments, Inc.’s optical mass monitors are lower cost, portable and semi-portable devices and are used in applications where indicative-level accuracy and precision are acceptable and where external power is not always available. These instruments may be used to supplement government operated, criteria-grade PM air quality monitoring networks in order to provide additional monitoring locations often in places that cannot easily accommodate a fixed air quality monitoring station or one does not currently exist, such as to support California AB 617. These instruments may also be used as stand-alone devices for fence line or emergency deployment monitoring applications. The optical mass monitors offered by Met One Instruments, Inc. are:

  • E-Sampler Dual Ambient PM Monitor/Sampler
  • ES-642 Remote Dust Monitor
  • NPM 2 Network Particulate Monitor
  • Radiance Research M903 Integrating Nephelometer

Met One Instruments, Inc.’s reference air samplers are available in either single-event or multiple event configurations. The single event E-FRM reference sampler is used for ambient sampling on pre-weighed 47 mm diameter filters for later gravimetric or chemical speciation laboratory analysis. The E-SEQ-FRM sequential reference sampler may be loaded with up to 16 pre-weighed 47 mm diameter filters for later laboratory analysis and provides for up to 16 independent sampling events. Our SASS and SuperSASS single and multiple event speciation samplers provide the capability of collecting five independent samples in a single event, or up to 8 independent samples on up to 4 independent sampling events. The SASS and SuperSASS speciation samplers use pre-weighed 47 mm diameter filters which may be used for gravimetric or speciation chemical analysis. The PM samplers offered by Met One Instruments, Inc. are:

  • E-FRM Reference Air Sampler
  • E-SEQ-FRM Sequential Reference Air Sampler
  • SASS Five Channel Single Event Speciation Sampler
  • SuperSASS Sequential Eight-Channel Speciation Sampler
