Air Quality Monitoring

The RAM 2000™ is an affordable, user friendly instrument that can provide real-time identification and quantification of over 250 chemicals and detection levels mostly in the range of 0.1 to 15 ppb (path-averaged). Unlike point monitors, it monitors an entire path up to 1000 meters in length, giving a vapor cloud little chance to pass through undetected.

The RAM 2000™ is the most advanced, practical method for gas monitoring along a fenceline. This Open-Path FTIR Analyzer can operate continuously and unattended while identifying and quantifying individual chemicals in gas mixtures.

When gases pass through the monitored path, the RAM 2000™ detects, quantifies, and reports the amounts of each chemical in real-time.

RAM 2000™ Applications

Emergency Response Monitoring in Case of Accidental Releases of Toxic Chemicals
Detection of Chemical Agents
Perimeter Monitoring of Facilities
Site Characterization
Source Monitoring and Emission Characterization
Remediation Monitoring for Workers' Safety and Downwind Impact

SYSTEM SOFTWARE

The RAM 2000™ unit is a remote chemical detection system used by petrochemical and pharmaceutical companies to monitor chemical emissions. The RAM 2000™ software, RMMsoft™, controls the RAM 2000™ system. State-of-the-practice software tools and methods, a SEI-compliant development process combined with advanced signal processing algorithms and an easy to use GUI interface resulted in the development of this easy to operate system.

The RMMsoft™ software was awarded the Long Island Software Award (LISA) for the most innovative software from the Long Island Software and Technology Network (LISTnet). We won for the large company category. LISTnet is an organization comprised of over 330 companies dedicated to promoting the Long Island Software industry.

Windows-based RMMsoft™ facilitates EASY-TO-USE OPERATION by nontechnical personnel as well as detailed spectroscopic analysis.

SPECIFICATIONS
