Normal Working conditions:

  • The Standard Operating Temperature:-25℃~+40℃
  • Storage: -60℃~+80℃
  • Altitude: ≤3000m. Less than 5000m for plateau type product
  • Under normal use, the limit humidity should not exceed 95% and last more than 24 hours, and measures to prevent condensation should be taken. Environmental humidity is correlated with temperature. When the ambient temperature is high, the relative humidity is required to be lower. If the temperature exceeds +40℃, the relative humidity is not more than 50%.

Packaging & Storage

Each product is packed separately and put into the carton box. The products should be stored at temperature no higher than +80℃, no lower than -60℃. No acidity, alkaline or other corrosive gas.
