CW Sentry
The CW Sentry Chemical Warfare Agent Detector measures the presence of CWAs and select TICs. The wall-mounted unit uses two separate detector arrays—SAW microsensors and an optional configuration of electrochemical cells—to detect nerve and blister agents, as well as TICs including hydride and halogen. An internal fan draws air into the unit, where it is filtered twice to prevent contamination from dust and dirt. The unit measures the air and transmits the results via a variety of methods, including Ethernet fiber optic lines, while also offering wireless functionality.
