ISO9001:2015 Quality Management System Continues to Run Effectively

The company first passed ISO9001 quality management system certification in 2002. For more than two decades the system has run continuously and effectively, with quality control embedded in every part of our operations.

The current certificate was issued by CQM (China Quality Mark Certification Group) under GB/T 19001-2016 / ISO 9001:2015, Certificate No. 00226Q05069R801-1, valid until August 11, 2027.

The certification scope covers the design, development and production of our four core product lines: expendable fast thermocouples, NG-series fast samplers, thermal analysis sample cups and fast oxygen sensors for liquid steel.

Based on this systematic quality management, we have established full-process control from incoming material inspection and in-process checks to final product testing, ensuring stable and reliable performance of every product. The original certificate can be viewed on the About Us page.
