Use conditions
1.Ambient air temperature: -40℃~+40℃
2.The altitude of the installation place is not more than 2000m above sea level.
3. Temperature and humidity conditions are as follows: the average value of relative humidity measured in 24H does not exceed 95%, the average value of water vapour pressure measured in 24 hours does not exceed 2.2Kpa, the average value of monthly relative humidity does not exceed 90%, and the average value of monthly water vapour pressure does not exceed 1.8Kpa, taking into account the condensation that occurs on the surface of the product due to temperature changes.
