China Testing & Certification Laboratory
2026-05-19
Project Overview
China Testing & Certification International Group Co., Ltd. (CTC Group) originated from the inspection and certification business of China Building Materials Academy in the 1950s. After decades of continuous development, the group has established five major business platforms covering inspection and testing, certification and evaluation, testing equipment and intelligent manufacturing, metrology calibration, and scientific research & technical services.
As a leading inspection and certification organization, CTC Group requires highly precise environmental control to ensure the accuracy and reliability of testing results.
To meet the strict laboratory requirements, Sunchine designed and supplied a customized constant temperature and humidity air conditioning system to accurately simulate controlled environmental conditions and support high-precision testing applications.
