Temperature Humidity Chamber

About Temperature Humidity Chamber

It is a sealed, insulated enclosure equipped with systems to precisely regulate both temperature and humidity. These chambers can reproduce a wide range of environmental conditionsfrom hot and humid to cold and dryallowing users to study how products behave over time.

Key Features

• Wide temperature range: Typically from 20C to +80C (advanced models may go beyond this range)
• Humidity control: Usually 20% to 95% relative humidity (RH)
• Digital/programmable controller: Enables setting constant or cyclic test conditions
• Heating and cooling system: Uses heaters and refrigeration units
• Humidification system: Adds moisture via steam or ultrasonic methods
• Dehumidification system: Removes excess moisture using cooling coils or desiccants
• Air circulation fan: Maintains uniform environmental conditions
• Observation window: For monitoring samples without disturbing conditions

Working Principle

The chamber operates by integrating multiple systems:

• Heating elements raise the internal temperature
• Refrigeration system lowers temperature when needed
• Water-based humidifier increases humidity
• Cooling/dehumidifying unit reduces moisture levels
• Sensors continuously monitor temperature and humidity, and a controller adjusts the systems to maintain the set values accurately

Uses

• Electronics testing: Performance under heat and moisture
• Pharmaceutical stability testing
• Automotive component testing
• Material research: Plastics, metals, rubber, textiles
• Food and packaging shelf-life studies

Types

• Benchtop chambers: Small-scale laboratory use
• Walk-in chambers: Large chambers for bulk or industrial testing
• Programmable (cyclic) chambers: Simulate varying environmental conditions over time
