Equipment Overview
This testing machine is mainly used for the influence of humidity and temperature changes that may occur during operation, storage or transportation of optical fiber interconnection devices, electronics, communications, and aerospace products. The sample is placed in the test box and subjected to several temperature-humidity cycles defined in the relevant specifications. During the entire test, the attenuation of the sample is monitored.
