Equipment Overview
It is used to make the test of high and low temperature, damp and heat tests on electrical, electronic, mechanical and large parts, semi-finished products, and finished products. To test the quality and productivity of products, spare parts under simulated temperature and humidity conditions.
Installation environment:
Temperature: 0℃～35℃, relative humidity: ≤85%, air pressure: 86kPA～106kPa.
Please confirm that the installation site should be level, well ventilated, and without strong vibration around the equipment. There has no strong electromagnetic filed, without flammable, explosive, corrosive substances and dust around this equipment. It should leave enough space for use and maintenance.
