What eyc-tech does

eyc-tech (legal entity: YUDEN-TECH CO., LTD.) is a Taiwanese private industrial sensor manufacturer founded in 2009 and headquartered in New Taipei City. The company designs and produces environmental sensing and measurement instruments spanning ten product categories: air flow and air velocity transmitters (thermal mass, hot-wire, Venturi, Pitot), temperature and humidity transmitters (capacitive, Pt100), dew point transmitters, differential pressure transmitters, ultrasonic liquid flow meters, pressure transmitters, level transmitters, air quality transmitters (CO2, CO, PM2.5), and signal meters/indicators. Sensing technologies include thermal mass flow, hot-wire anemometry, capacitive humidity sensing, ultrasonic time-difference flow measurement, and piezoresistive/ceramic pressure sensing. eyc-tech operates a TAF ISO/IEC 17025 accredited calibration laboratory (certification number 3032) traceable to international standards and a 3,000 square meter production facility expanded in 2022 with automated dew point, temperature/humidity, and airflow calibration equipment.

The company's commercial focus is on semiconductor manufacturing (wafer etching exhaust monitoring, cleanroom pressure), data center and AI server liquid cooling (coolant flow measurement), HVAC and building management, industrial automation and compressed air, cleanrooms and pharmaceuticals, water and wastewater, and smart agriculture. eyc-tech sells through a global premium distributor program, an online shop on TaiwanTrade, and direct enterprise inquiries, and actively recruits regional distributors in markets including the Philippines (Dubeon Corporation, 2022). Revenue is generated primarily through one-time hardware sales of industrial transmitters with minimum order quantities of 10-100 units per SKU per year; OEM/ODM customization is offered. The company is independently owned (no parent, no disclosed external funding) and reports ISO-9001:2015 quality management certification (since 2009, renewed 2023), CE marking, and TAF laboratory accreditation. Recent strategic activity centers on product launches in 2025 (THM50X, THS88ECO, PMM06-D, FUM06) targeting semiconductor and AI infrastructure applications.
