In the production process of the textile workshop, temperature and humidity have an important impact on fiber materials and product quality. The temperature and humidity field inspection instrument can monitor changes in temperature and humidity in the workshop. For materials such as cotton fibers, improper humidity will affect its spinnability, and unstable temperature will affect indexes such as yarn strength. The inspection instrument can help workshop managers to timely adjust temperature and humidity parameters, and optimize the production environment through means such as ventilation, humidification or dehumidification to improve the quality and production efficiency of textiles.
