Temperature Humidity Test Chamber

This chamber is built for routine reliability testing, product validation, and quality inspection. It provides controlled temperature and humidity environments for both constant and cyclic test programs.

Key features:

• •High temperature and low temperature testing.
• •Constant temperature and humidity control.
• •Damp heat and humidity resistance testing.
• •Alternating temperature humidity test programs.
• •Stable environmental simulation for repeated tests.
• •Suitable for standard laboratory and production QC use.

Temperature and humidity changes can cause electrical instability, material aging, deformation, corrosion, coating failure, sealing problems, and performance drift. This chamber helps engineers identify these risks before products enter mass production or field use.

Typical applications:

• •Electronic components and PCB reliability testing.
• •Automotive electronics and instruments.
• •Communication products and consumer electronics.
• •Plastics, rubber, metals, coatings, and packaging materials.
• •Sensors, connectors, switches, and control modules.
• •Home appliances and industrial components.
• •Material research, quality inspection, and incoming material validation.

The chamber uses a programmable control system to support repeatable test profiles and stable environmental simulation. Users can set temperature, humidity, constant operation, and cyclic programs according to product requirements or test standards.

Control features:

• •Programmable touchscreen controller.
• •Multi-step temperature and humidity profiles.
• •Constant and cyclic test modes.
• •Optional RS232, RS485, or Ethernet communication.
• •Optional PC monitoring and data recording.
• •Alarm protection for abnormal operation.
• •Multi-language interface available by configuration.

Stable refrigeration, humidification, dehumidification, and airflow design are essential for accurate climatic testing. SANWOOD designs the chamber to support temperature and humidity uniformity, stable recovery, and long-term operation.

System highlights:

• •Built-in refrigeration system.
• •Stable humidification and dehumidification control.
• •Optimized airflow for chamber uniformity.
• •Hot-gas defrosting option depending on model.
• •Modular refrigeration design for easier maintenance.
• •Energy-saving control logic available by configuration.
• •Durable structure for repeated temperature humidity cycles.

Final configuration should be selected according to temperature range, humidity range, chamber volume, sample heat load, cooling rate, and ambient conditions.

The chamber can be configured to support test conditions related to common temperature and humidity testing methods, including IEC 60068-2-1 low temperature, IEC 60068-2-2 dry heat, IEC 60068-2-30 damp heat cyclic, IEC 60068-2-78 steady-state damp heat, ISO 16750 automotive electronics, and MIL-STD-810 environmental testing.

Final compliance depends on the complete test method, sample type, calibration status, sensor setup, operating procedure, and third-party assessment.

Customization options:

• •Chamber volume and inner dimensions.
• •Temperature and humidity range.
• •Cooling rate and heating rate.
• •Viewing window and cable port.
• •Communication and data recording.
• •Sample rack or fixture.
• •Power supply by destination country.

SANWOOD Technology can provide model selection support, customization guidance, installation assistance, maintenance, repair, and technical service according to project requirements.
