Our Mission
To become the world’s most reliable and professional provider of testing solutions.
Our Journey
ZKSSUN originated in Japan and has developed into a global enterprise with 8 major laboratories worldwide. Our headquarters is located in Chongqing, China.
We design, manufacture, sell, and support both U.S.-engineered models and select environmental chambers from our Japanese parent company. Our manufacturing facility covers an area of 60,000 square meters and operates under a strict ISO 9001:2015 certified quality management system.
With nearly 60 years of experience in environmental test equipment manufacturing, our product range covers everything from small standard test chambers to large customized environmental simulation laboratories.
Quality is not an option—it is embedded into every stage of our process and built into every system we deliver. It is the foundation of our growth strategy and long-term success.
As we continue to expand globally, we have also established specialized HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) laboratories, providing dedicated environmental testing service spaces for advanced reliability validation.
