INTRODUCTION
This constant temperature and humidity chamber for textiles is a scientific instrument used in the field of textile testing. It ensures testing accuracy by precisely controlling environmental parameters. Its core function is to maintain specific temperature and humidity conditions; as of December 2020, it could operate stably within a temperature range of 23℃±2℃ and a humidity range of 50%±5%. This equipment has significant application value in textile quality inspection, materials research and development, and other scenarios.
