MR-ACT Gas Telemetry Imaging Early-Warning System Model: MR-ACT Designed for the protection of people, plants, and communities, the MR-ACT gas telemetry imaging early-warning system provides continuous, non-contact detection of dangerous industrial gases at a distance. Its sensing approach is grounded in infrared spectroscopy and brings together a high-accuracy interferometer, an infrared detector, and a dedicated processing circuit. As a result, the system can distinguish
