Baier Water Quality Testing Services
Water is an indispensable material resource for human survival and development, and the safety and quality of water affect all aspects of people's daily lives and industrial production.
As a third-party testing institution qualified with CMA (China Inspection Body and Laboratory Mandatory Approval) and CNAS (China National Accreditation Service for Conformity Assessment), our water testing services cover four core scenarios: domestic use, industrial use, agricultural use, and environmental use. All categories of testing are conducted in compliance with relevant national standards to ensure the data is legally valid and reliable.
