Analysis and assessment
The analysis and assessment are managed in accordance with corresponding requirement recognized by national lab. We provide analysis for physical and chemical performances of lubricant, bench test, examination and analysis of samples. We also provide monitor service. We have various analyzer over 20 and dozens of assessment items. The test result is accurate, redivivus and authentic.
