Working Principle

The Double 85 Test Chamber achieves stable high-temperature and high-humidity environment through 5 core modules and PID closed-loop control, ensuring long-term stable test conditions. For more details on Double 85 test chamber working principle, our technical team provides professional consultation.
  • Sealed Insulation Chamber: Double-layer stainless steel + insulation cotton, highly sealed and heat-insulating to prevent heat and moisture leakage and ensure internal environment stability.
  • Heating System: Equipped with electric heating tubes, providing constant 85℃ high temperature, with PID precise adjustment for minimal temperature fluctuation (±0.5℃).
  • Humidification System: Adopting shallow tank or steam injection humidification, quickly raising air humidity to 85%RH with uniform effect.
  • Dehumidification & Humidity Control System: Cooperating with compressor to condense excess vapor, linking temperature and humidity control to stably lock 85%RH.
  • Strong Air Circulation System: Built-in fan and air duct, realizing 360° uniform temperature and humidity distribution to ensure consistent sample test results.
