MSA's portable gas detection is moving from standalone beeping hardware to connected worker devices and MSA Plus subscription software that alerts nearby workers and central supervisors, automates incident reporting, and improves safety. This creates recurring, higher-margin revenue and more revenue per device over its lifespan, plus a share-gain opportunity because MSA has a large installed base, durable owned-sensor hardware, and is one of only three scale competitors with connectivity.
