SASS®2400
Low-Volume Wetted-Wall Air Sampler
The SASS® 2400 LV air sampler is our smallest wetted-wall aerosol particle collection system. It is designed to operate with a much lower air flow and fluid sample volume than the SASS 2300, while still employing the highly successful wetted wall aerosol collection strategy that has received U.S. Department of Homeland Security Certification under the U.S. Safety Act of 2002.
The cyclone used in the SASS 2400 operates at a 40 LPM air processing rate and requires only 1 ml of fluid, whereas the larger SASS 2300 processes 325 LPM of air and requires 4 to 5 ml of sample fluid. Water loss through evaporation is correspondingly reduced. Makeup water sources will last longer, or can be reduced in size.
Extremely long collection periods continue to be a product highlight — sample fluid is maintained at a constant amount independent of collection time, ambient air temperature, or relative humidity, providing unsurpassed monitoring capabilities in environments ranging from farmyards to hospitals to battlefields.
Proven in Extensive Field Testing
Successfully tested and used in subway systems, public health facilities, nuclear power plants, corporate mail rooms and poultry ranches.
Virtually Unlimited Sampling Time
The SASS 2400 can operate unattended for extended time periods, from several hours up to even several days.
Unrivalled Power Efficiency
Running at near-peak fan efficiency, the SASS 2400 offers the longest possible battery operating time, allowing extended field use.
