Product Description

Features :

  • Precise temperature controlled, high humidity environment. Water held in a sump located in the cabinet base, is heated by an immersion heater to generate water vapour.
  • As water vapour evaporates, it saturates the cabinet atmosphere with moisture. Test samples in the cabinet, below the dew-point temperature of the saturated air, will develop surface condensation.
  • By careful design the high humidity environment is achieved without the need for a circulation fan, which would otherwise have to endure the hostile, high humidity environment.
  • Safety cut-outs ensure the immersion heater is automatically isolated if the water reservoir runs dry.
  • User can program either a single set temperature, or automatically cycle the cabinet temperature between two different temperatures for user defined periods of time.
  • Automatic filling and topping up of the humidity water reservoir if connected to a pressurised water supply.
