Founded in 1989 — a smelting sensor and temperature instrument brand you can trust.
Company Profile
Nanjing Xinqiyuan Detection Equipment Co., Ltd. was founded in 1989 (formerly Nanjing Xinqiyuan Automation Instrument Factory) and is located at No.340 Yangxin Road, Dachang, Jiangbei New District, Nanjing. We develop and manufacture smelting sensors and intelligent temperature instruments for molten metal temperature measurement, sampling and cast iron carbon-silicon composition analysis.
The company is a council member of the China Smelting Sensor Association and a member of the Jiangsu Foundry Association and the Ma'anshan Foundry Association. It passed ISO9001 certification in 2002, and its fast thermocouples, fast samplers and thermal analysis cups have earned 6 utility model patents and 1 invention patent. Products sell across 19 Chinese provinces and are exported to Malaysia, Pakistan, Turkey, Thailand, South Korea, Vietnam, Oman and beyond — serving 300+ customers in steel, non-ferrous metals and foundry industries.
