5. Decent experimental environment.
To ensure the reliability of the developed products, the center set up two well-equipped, high-standard laboratories on an area of 500 square meters. One is used to test regular features and performance. The other is used to perform performance tests under extreme circumstances.
Despite the high costs, we bought complete devices to enable the experimental process from the simulation of the spot environment through the acquisition of technical data to digitized, visualized and traceable data processing and technology analysis. Every sample product is no longer a sample, but a device with practical application, and every data is no longer laboratory data, but highly simulated point data. In this way, we generally guarantee the data accuracy on site and the full-time reliability of the products.
