What Seristine Group does

Seristine Group is a Kunshan, China-based environmental testing equipment manufacturer operating as a relatively controlled subsidiary of Tianrui Instruments (Shenzhen Stock Exchange: 300165). The company develops and sells a broad portfolio of environmental simulation and climate testing chambers covering thermal shock, constant temperature and humidity, accelerated life testing (HAST), salt spray corrosion, walk-in environmental laboratories, fast temperature change stress screening, and online glove-type test systems. Equipment volumes range from 50L bench-top units to 24,000L walk-in laboratories, and the product line targets industries including semiconductor and electronics manufacturing, ICT (5G, optical fiber, data centers), aerospace, automotive, medical devices, and biotech.

Technically, the company differentiates through a self-developed control system, an ultra-fast thermal shock technology capable of -40°C to +85°C transitions in approximately 10 seconds, a zero frost function for long-term low temperature operation, and a three-box thermal shock architecture with pneumatic air door switching. Its equipment conforms to international standards including GB/T2423 series, MIL-STD-810G, MIL-STD-202G, GJB-150-A, IEC 60068, and JESD22-A106B, and the company holds ISO 9001, ISO 13485, and EU MDR certifications, supporting defense, aerospace, and medical device customer requirements.

Seristine operates a B2B, sales-led go-to-market model with direct sales from its Kunshan headquarters and a network of authorized distributors across 60+ countries. Revenue is generated through hardware sales of standardized chambers plus customized solutions, with quote-based pricing that is not publicly disclosed. Marketing is concentrated in industry trade shows (notably CIOE) and industry platforms such as Xunshi (讯石) for the optical communications vertical. Disclosed reference customers include Chinese Academy of Sciences, Military Research Academy, and Quality Inspection Centers, indicating material exposure to government and quasi-government procurement alongside enterprise commercial customers.
