Precautions for use

  • Kindly remove the protective film before usage.
  • To prevent exposure to volatile silicon compounds vapors (such as silicone adhesive, hair gel, silicone rubber, or other locations where volatile silicon compounds are present).
  • Avoid exposure to high concentrations of corrosive gases (such as H2S, SOX, Cl2, HCl, etc.).
  • Prevent contamination from alkalis, alkali metal salts, and halogens.
  • Refrain from prolonged exposure to extreme environments (such as high temperatures, high humidity, high pollution).
  • Avoid contact with water, condensation, and freezing.
  • Minimize excessive vibration, impact, and dropping.
  • Please refrain from employing this module in systems that involve personal safety concerns.
  • For extended periods of non-usage, it is advisable to preheat the module for at least 24 hours.
