General Description
HGVI (Hazardous Gas and Vapor Identifier), designed for first responders to identify high level threats, is the first handheld instrument that simultaneously detects, identifies, and quantifies CWA’s and TIC’s. It also incorporates a gamma radiation detector to warn the operator of radiation threats that may be encountered. Handheld and weighing only 7.5 pounds (3.4 kg), HGVI can be easily carried into the Hot Zone with its shoulder strap, freeing up both hands to do other duties. As soon as the incident is cleared the HGVI can be removed from the Hot Zone and decontaminated by simply turning the system off and wiping the exterior with a bleach-soaked cloth. HGVI is simple to operate and designed with input from Emergency Responders. The system features an easy-to-see LCD screen with an integrated light sensor that automatically adjusts the backlight based on lighting conditions. Intuitive software, one-handed operation during use, and multiple alarms make the system ideal for use in all types of environments. HGVI also includes an integrated GPS receiver and wireless modem for use with the optional HGVI LINX accessory, which can be used to monitor up to 16 HGVI units and display their locations on industry-standard street maps.
Technical Description
HGVI has extended the usefulness of its core IMS technology by also incorporating a Photoionization Detector (PID) and an array of Taguchi Gas Sensors (TGS) that are integrated into the system. The IMS module in HGVI contains a non-radioactive source and parallel positive and negative ion paths. The use of a chemically doped sieve pack provides state-of-the-art interference rejection for a handheld IMS. The PID contains a 10.6-eV ionization bulb that makes it responsive to most volatile organic compounds. The array of six TGS’s allows the system to detect a very broad range of gases and vapors and provides a rough chemical signature for each substance. HGVI’s H-Fusion Decision Enhancement Software combines the data from the system’s three orthogonal chemical sensor modules to rapidly and automatically provide identification and quantitation. This data fusion facilitates greater discrimination of materials and reduces the number of incorrect identifications typically associated with IMS technology.
