Features

• Significantly shortened testing time
  This chamber achieves a temperature recovery between +125°C and -40°C only in 3 minutes by high air velocity and unique air flow control which reduce testing time approximately 1/3 compared to conventional models.
• Ensures correlation with thermal shock testing
  Enables more efficient evaluations by retaining test accuracy.
• Defrost-free with no test interruptions
  No interruptions required during testing for defrosting with a defrost-free function which prevents from frost.
  Saves time and power consumption for defrosting.
• Available for conventional thermal shock testing
  Enables to perform conventional thermal shock testing by equipping with a air flow adjuster for allowing reduction of air velocity.
  Provides a variety of thermal shock testing with a variety of evaluation conditions flexibly.
