US-EPA Certified, 5 & 8 Channel Gravimetric , Flow Rate 6.7 liter/min

 Two models provide a choice for compliance monitoring: SASS is a 5 channel sampling system and SUPER SASS is 8 channel, multiple event sampling system. The SASS conforms to original EPA requirements and SUPER SASS adds benefits suggested by state and local authorities.

Both models use concepts pioneered by Met One Instruments, such as the contamination free Canister, solar radiation shield, and modular design. SASS and SUPER SASS not only comply to EPA specifications they exceed the specifications, as proven in EPA and California Air Resources Board field studies

SASS
• Portable integrated ambient particulate sampling system
• Inlet for PM2.5 at 6.7 liter/minute sample rate
• Solar shield maintains cassettes to less than 5°C over ambient temperature
• Canister provides data integrity - contamination proof
• New multi-cell denuder and multiple filter medias

SUPER SASS
• Up to 8 Channel Operation
• One to Eight day Sampling, Sequential
• Automatic Volumetric Flow Controllers
• Each Channel may be operated independently
• Advanced Field Audit Screens
