Wireless MeshGuard EC Gas Detector

MeshGuard Wireless EC Sensors

Semi-Fixed, Wireless Gas Monitor

The MeshGuard is a battery operated, semi-fixed, wireless monitor for gas and gamma radiation.* An internal mesh radio allows it to form an intelligent network for enhanced safety without costly wiring. MeshGuard systems can easily be configured for a broad range of applications. The MeshGuard easily connects to a controller and/or wireless alarm bar.

Meshguard EC

Wireless gas detector with six-month continuous runtime for hazardous environments

Remotely monitor toxic gases using the most advanced gas detection technology and connected data systems. The wirelessly connected mesh-radio based MeshGuard EC is a core component of the MeshGuard network of connected sensors.
MeshGuard EC is rugged, reliable, and designed for rapid deployment. It runs for up to six months on a single battery and provides continuous detection and measurement of potential threats even in hazardous work environments such as oil and gas rigs, industrial sites, and refineries.
The MeshGuard EC intelligently finds the best available path to establish a self-forming, self-healing wireless network and delivers all sensor and alarm data to the RAE Systems controller of your choice. The device also displays the information on the large, back-lit LCD screen and has integrated audible and visual alarms. The MeshGuard EC is intrinsically safe, IP-65 rated weather resistant, and certified for the most hazardous, Class 1, Division 1 or Zone environments.
