"Sigma Humidity Solution" Chambers are precisely temperature and humidity controllable convection ovens in which items can be placed for heating or cooling at specific humidity values.  Sigma Systems unique “Humidity Generator” enables humidity testing with minimal condensation or DUT contamination. Our patent pending design humidifies air from the chamber with treated water and returns it to the chamber at temperature. The Sigma design avoids super-heated steam injection and water sprays that cause temperature fluctuations and condensation of up to 40% of the water vapor.

The Sigma “Humidity Generator”:

• Minimizes condensation to reduce testing errors, DUT failures, and safety
   exposures related to liquid water in and around the chamber
• Eliminates DUT degradation caused by super-heated organic compounds
   introduced by steam injection humidifiers
• Provides consistent test results by maintaining stable set points and creating
   smoother RH% and temperature transitions
• Reduces test times by actively reducing RH% during transitions to lower
   temperatures or RH% settings.

Specifications

• Humidity temperature range +5°C to +98°C
• Dry temperature range –100°C to +170°C
• RH% range 5% to 95%
• Supports direct potable water source connection
• 100 hours operation on optional internal water supply
   (for units not direct connected)
• 5 micron, adsorptive, and absorptive water decontamination system
• Available in chambers from 3 to 15.6 cubic feet
