800-HCB, Humidity Control Box
How It Works:
Set your desired humidity level and the humidity control box controls and monitors the humidity level within the main working chamber. If the moisture level is above the set point, the controller turns on the circulation pump and flows air through the drying train canisters. Once the desired humidity level is reached, the controller turns the pump off. If the moisture level is below the set point, the controller turns on the nebulizer to increase the humidity.
Types of Humidity Control Boxes
800-HCB uses the installed drying train system for dehumidification.
800-HCB/IG uses your source of inert gas for dehumidification. If the moisture level is above the set point, inert gas flows through the glove box and maintains a slight positive pressure. Once the desired humidity level is reached, the controller shuts off the gas. If the moisture level is below the set point, the controller turns on the nebulizer to increase the humidity.
Basic features include:
- Digital controller

Humidity and Temperature Analyzer
Model 800-RH/HH is an ideal everyday spot-checking tool for glove box users The sensor provides reliable measurement while the user interface with graphical trend display makes daily operation quick and easy. User interface is available in 10 languages.
In addition to relative humidity and temperature, the 800-RH/HH can display five calculated humidity parameters (absolute humidity, dew point, enthalpy, mixing ratio, wet bulb), all available in both metric and non-metric units. The 800-RH/HH features an interchangeable measurement probe allowing for easy calibration (only the probe needs to be calibrated) or replacement of the probe.
