RH/Temperature Stability Chamber

RH/Temperature Stability Chamber
No. 2148-10A, shown with optional stand.
humidity level critical
This acrylic cabinet is customized for storage of polycarbonate films used for high-precision screening of circuit boards. It maintains critical relative humidity and temperature levels to prevent dimensional aberrations that result from exposure to humidity and temperature fluctuations.

Humidity Accuracy:
± 3%RH within ± 20% of ambient
Temperature Accuracy:
± 2°F (-18.9°C to -16.7°C) within ± 10°F (-23.3°C to -12.2°C) of ambient

Air circulates horizontally across the shelves that hold the film. As air exits the storage area, it passes through an air conditioning/heating module that conditions it to within ±2°F (-18.9°C to -16.7°C) of the temperature set point. In addition, the continuously operating A/C module removes moisture to keep the %RH level within ±3% of the set point. If humidity falls too low, an ultrasonic humidifier cycles on to add the proper amount of water vapor. If the temperature falls too low, the heater module cycles on. A water filtration system removes contaminants from the humidification feed water to eliminate the chance of mineral deposits or other vapor-borne contaminants.

As the process air exits the RH/temperature modules, an impeller blower draws it into an intake plenum area and forces it uniformly back through the storage area.

Nitrogen generator Nitrogen Generators give you a reliable point-of-use supply of up to 99%-pure nitrogen. Eliminate the drawbacks of canisters and 3rd-party suppliers! You control volume, purity and rate; all you need is a clean compressed-air feed. Terra's three sizes of maintenance-free membrane generators meet several capacity requirements are are ideal for back-filling or continuous flow into desiccators, glove boxes, vacuum chambers and incubators.
