Low Humidity Steady State Test Chamber

Home > Low Humidity Steady State Test Chamber



The Chamber is used to carry out Low Humidity Steady State Tests at any temperature within specified limit. Though it is not suggested by any standard, some laboratory wants to simulate too dry condition

Test Conditions :

  • Temperature: 50 C to 500 C
  • Relative Humidity: 5% to 30% Rh
  • Lower Dew Point Temperature: -250 C
