Windtuner's Testing Center exemplifies that standard. As the first privately operated laboratory in China accredited by the China National Accreditation Service for Conformity Assessment (CNAS), Windtuner boasts three wind tunnel labs that provide calibration results with full international recognition. Its mission is to ensure that every data point engineers rely on is verified, consistent, and trustworthy.
‘Precision is more than a marker; it's the foundation of experimental truth,’ says a senior engineer at Windtuner. ‘Through accredited calibration and advanced automation, we help our partners achieve dependable results in the world's most demanding environments.’
The Windtuner Wind Tunnel Laboratory
I.Setting the Benchmark for Accredited Calibration
Windtuner's Testing Center holds CNAS accreditation (Certificate No. L18893) and performs calibrations in strict accordance with JJG 875-2019 'Verification Regulation of Digital Pressure Gauges', and JJF 329-2022 'Calibration Specification for Pressure Scanners'. Each certificate carries the CNAS mark, validating its traceability and global recognition.
The strength of these wind tunnels lie in their technical expertise and advanced instrumentation. Windtuner's team of PhDs, engineers, and certified metrologists combines rigorous theoretical grounding with extensive field experience. The facility features ConST81JA automatic pressure calibrators, intelligent pressure controllers, and high-low temperature chambers capable of 0.01-class accuracy across multiple pressure and temperature ranges.
II.Automation and Transparency at Every Step
Windtuner proccesses its calibration whilst ensuring complete control and traceability:
Request and intake: Clients submit calibration needs; the center defines technical requirements.
Sample registration: Devices are logged, labeled, and verified against the calibration plan.
Automated calibration: Standard instruments conduct precise measurements on sensors, circuits, and interfaces.
Data verification: Automated collection and multiple cross-checks eliminate human error.
Report issuance: A CNAS-marked calibration certificate is issued following comprehensive review.
III.Fast, Reliable, and End-to-End Service
Windtuner provides a complete service ecosystem with:
- 24/7 response and certificate delivery within one week;
- Fully automated calibration, minimizing human interference and improving repeatability;
- Extended maintenance support, including sensor recalibration, circuit testing, and interface validation to maximize equipment longevity.
