Wetsys

The highlights

Controlled Humidity Generator

The WETSYS is a stand alone, simple and robust system designed to generate atmospheres with a controlled humidity level.

HIGHLIGHTS include:

  • Accurately controlled atmospheres with humidity levels up to 95% RH
  • Operations with gases such as air, He, Ar, N2, CO2
  • A heated transfer line with a standard connection for coupling to SETARAM thermal analyzers and calorimeters, to third party instruments, or to climate chambers
  • Analog outputs for RH and temperature data acquisition
  • An optional external relative humidity probe for in-situ RH regulation

Applications

Humidity is known to considerably affect the properties of many products such as energetic materials, polymers, pharmaceutical materials, foodstuff, plasters, cements, thermal energy storage materials, metals and alloys, etc.

To evaluate the influence of humidity on the properties or long term stability of these products, it is necessary to study their specific behavior under relative humidity controlled atmospheres.
