MeshGuard is the leading gas detection system that is rapidly deployable in numerous industrial and remote monitoring applications. MeshGuard not only saves lives, but tens of thousands of dollars in regulation compliance and information processing. MeshGuard is fully supported by the ProRAE Guardian software platform.

MeshGuard combines the most advanced gas detection technology for industrial safety applications with the latest in connected data systems. Because the system includes powerful wireless sensors that can be deployed rapidly in any environment, MeshGuard eliminates the need for lengthy and costly installation projects. By detecting and recording a wide range of deadly gases and quickly relaying the data to an easy-to-understand central system, safety personnel have up-to-date information from throughout the network of sensors at a finger’s touch.
