China Testing & Certification International Group Co., Ltd. (CTC, Stock Code 603060) originated from the testing and certification business of China Building Materials Academy in the 1950s. After 70 years of unremitting efforts and persistent pursuit, the company has formed five business categories: detection and testing, certification and evaluation, testing instruments and intelligent manufacturing, measurement and calibration, scientific research and technical services, committed to providing customers with technical services and comprehensive solutions of detection and testing, certification and evaluation, appraisal, consultation, training, and instruments and equipment in fields of quality, environmental protection, green, safety, health, and energy conservation.

The construction, operation, and maintenance (O&M) services for automatic monitoring facilities at key polluting source enterprises represent a key initiative in China’s environmental management transition from “manual supervision” to “technical supervision,” enhancing the capacity for precise and scientific pollution control. The core principle involves using automated monitoring equipment installed at discharge outlets to continuously and real-time monitor pollutant emissions. Data is linked to environmental protection departments via data acquisition and transmission units, forming an efficient remote supervision network.
