| Research International, Inc. - RSN 5000

General Description
Research International's Remote Sensor Node 5000 (RSN 5000) is a portable CBRN monitoring device suitable for the detection of toxic gases, aerosolized biological agents, and nuclear materials. It is the only product of its kind currently available in the world, integrating detection technologies from the world's leading suppliers into a complete, networked CBRN monitoring solution. It has been developed for use in military, homeland security, public safety and public health applications. Some sensors are mounted within its tough cylindrical aluminum shell of 20 cm diameter and 1 meter height, others, including GPS and a weather station, mount on the outside, while other sensors, such as video or thermal IR cameras, can be mounted nearby and connected to the node via wireless. A built-in tripod is used to position the unit or it may be secured to structure using locking rings built into the exterior surface. Portable anti-theft features similar to those used for automobiles have been incorporated to protect the unit during unattended operation.

Technical Description
The RSN 5000 is modular in design and is constructed to customer requirements.

Available sensors include:

One or more of four state-of-the-art chemical detectors.
An ultraviolet fluorescence-based biological particle detector for suspicious changes in bioaerosol concentrations.
A sensitive gamma ray detector that detects suspicious changes in background radiation.

The RSN 5000 normally operates in a background monitoring mode, sampling air at 200 liters/minute. The air stream can be analyzed with an ion mobility spectrometer to detect and identify chemical warfare agents. It can be further analyzed with an array of 6 electrochemical gas detectors for common toxic industrial chemicals. A gamma ray monitor is used to detect radiation in the air sample. Finally, this air sample is tested for suspicious increases in bioaerosol concentration with the TacBio bioaerosol monitoring instrument. If an instrument alarms (or under remote control), a secondary sampling line,based on the SASS 3100 dry air sampler, is activated that collects particulates onto a proprietary electret filter for later analysis of captured biological or other particulates.
