Senko Co., Ltd. is a South Korea-based technology company primarily engaged in the development, manufacturing, and distribution of electrochemical gas sensors, industrial safety instruments, and IoT-based environmental monitoring systems. Founded in 2004 and headquartered in Osan-si, Gyeonggi-do, South Korea, the company operates across three primary business segments: Gas Sensors, Industrial Safety Equipment, and Environmental Measurement Solutions. Its core product portfolio includes electrochemical gas sensors designed to detect hazardous gases such as carbon monoxide, hydrogen sulfide, oxygen, sulfur dioxide, nitrogen dioxide, ammonia, and volatile organic compounds; portable single-gas and multi-gas detectors marketed under the SGT, MGT, and SP series; fixed gas detection systems, flame detectors, and explosion-proof transmitters for harsh industrial environments, including the SI-100 series; smart air quality and odor monitoring stations for real-time atmospheric surveillance; and integrated IoT safety management platforms for smart city and industrial complex monitoring. The company caters to clients across diverse sectors, including petrochemicals, semiconductor manufacturing, shipbuilding, steel production, mining, public utilities, and energy storage systems across domestic and international markets in North America, Europe, and the Asia-Pacific region. In recent developments, Senko Co., Ltd. has accelerated its strategic expansion into clean energy and advanced mobility sectors by developing specialized gas detection sensors for electric vehicle battery thermal runaway prevention and hydrogen leak monitoring for hydrogen infrastructure. Additionally, the company has expanded its global commercial footprint through new distribution partnerships and OEM supply agreements with overseas safety equipment providers, reinforced its environmental monitoring division through strategic acquisitions and technology alliances in specialized odor analysis, and advanced its high-precision sensor line for semiconductor cleanroom monitoring.
