Humex™ Humidification System

humidity sensor
High-capacity models available for humidifying
a large work area—call Terra
  • Humidifies process gases (such as air or nitrogen) to produce precisely controlled moisture levels between ambient and 100% RH in a processing chamber
  • Includes humidity sensor and automated controller with %RH display for continuous humidity monitoring
  • Can be used with a Dryex™ or Nitrogen Generator to alternate low- and high-humidity conditions
  • Ideal for conducting failure tests on moisture-sensitive components in a processing chamber
  • Recommended for enclosures of 60 - 200 cubic feet (1.7 m³- 5.6 m³)

The Humex Automatic Humidifier allows controlled moisture testing in an atmospheric chamber. It is ideal for determining failure rates of materials in many industries, from microelectronics to pharmaceuticals to cosmetics.

All-In-One Design Simplifies Operation

The Humex controller module houses all the components necessary for maintaining a pre-set moisture level in a remote processing chamber. To begin operation, you simply determine the desired humidity setpoint for your processing chamber by adjusting the control knob on the front panel; a 3.5-digit LCD display indicates this humidity setpoint for easy reference.

During operation, steam generated through controlled heating of water from an internal reservoir is routed to a gas supply line and then on to a process chamber (not included). There, the Humex™ fast-response, capacitive-type sensor detects the relative humidity level and feeds this information back to the Humex display to allow continuous chamber monitoring. The moment the humidity level falls below the user-defined setpoint, additional steam is generated and directed into the incoming gas line. When the setpoint is reached, the water supply to the heating element is shut off to halt steam generation. Automatic water level controls inside the water reservoir ensure a safe water level, and overtemperature protection maintains safe heat and vapor pressure.

Select a model for 110VAC or 220VAC operation. The system includes a 304 stainless steel housing containing a heating unit, stainless steel water reservoir with automatic water level controls, an automatic humidity controller, and a 3.5-digit LCD display. Order the fast-response humidity sensor separately (see specifications and ordering information below). A 0.375" (10 mm) stainless steel bulkhead fitting allows connection of a process gas line.
