21 Senses Inc.
Take over account

21Senses develops solid-state and MEMS-based hydrogen and multi-gas sensing technology used for safety monitoring and process optimization across the hydrogen value chain. Its sensors detect hydrogen concentrations as low as 1 ppm with fast response times, serving applications such as electrolyzer leak detection, fuel cell safety monitoring, hydrogen refueling, and hydrogen-cooled power generators. The company offers both fixed and portable hydrogen leak detectors as well as online multi-gas analyzers, designed to withstand high moisture and high-hydrogen-exposure environments. 21Senses also builds an IoT-enabled data platform that unifies sensor outputs to support predictive, real-time decision-making for hydrogen supply chain and mobility customers.
