Products Description
The integrated shutter box is made of high-quality UV-resistant material, with small size, light weight, good linearity, good waterproof performance and long service life. It is widely used in meteorology, environmental protection, agriculture, scientific research, highways, construction sites, industry, forestry and other departments. It is used to measure parameters such as carbon dioxide, temperature and humidity, light, and atmospheric pressure.
