What Sentech Korea does

Sentech Korea Corp. is a South Korean designer and manufacturer of semiconductor gas sensor systems and breath alcohol testing devices, headquartered in Paju-si, Gyeonggi-Do, and operating since 1998. Its product portfolio spans professional screening units (iblow10 Pro), evidential and ignition interlock systems (ALX3000), and the connected ADBs IoT breathalyzer, all built on the company's proprietary Suracell™ fuel cell sensor technology and sold under the ALCOSCAN brand. The company also distributes the iSOBER consumer mobile application as a software adjunct to its hardware. Sentech's revenue is generated primarily through unit sales of certified breath alcohol testing hardware, with a secondary software/connectivity contribution from iSOBER and ADBs.

The company sells into four end-customer segments: law enforcement and evidential testing, government-mandated ignition interlock programs, automotive OEM integration, and consumer/ workplace screening. Go-to-market is overwhelmingly indirect, executed through a network of 50+ distributors across the Americas, Europe, Asia, Africa, and Oceania, supplemented by owned regional offices in Germany and the United States for direct sales, service, and program management in the two largest Western markets. The distributor model is the principal revenue mechanism, with no disclosed subscription or recurring-services pricing beyond the iSOBER app.

Sentech's commercial positioning is anchored in a deep regulatory and certification stack — CE, DOT/NHTSA, EN15964, EN50436, FDA 510(k), and IATF 16949 — which together qualify its devices for use across ignition interlock, evidential, automotive OEM, and medical-screening end markets. Sourcing of the fuel cell core technology is in-house via Suracell™, reducing dependency on third-party sensor suppliers and providing technical defensibility. The company is privately held, has not disclosed external funding, and operates with a headcount of 11-50 employees, indicating a small, mature industrial business rather than a venture-backed growth company.
