Double 85 Temperature Humidity Test Chamber

The chamber is built for stable double 85 test conditions, helping engineers evaluate how products behave under continuous heat and humidity stress.

Key features:

• •Stable 85°C / 85%RH test environment.
• •Suitable for long-duration damp heat testing.
• •Constant temperature and humidity control.
• •Designed for reliability, aging, and durability validation.
• •Helps identify humidity-related failure risks.
• •Suitable for R&D, quality control, and certification preparation.

This test condition is often used to accelerate moisture, heat, corrosion, insulation, and material degradation risks before products enter mass production or field use.

Double 85 testing is widely used when products may face long-term heat and humidity exposure during storage, operation, transport, or outdoor service.

Typical applications:

• •Electronic components and PCB damp heat testing.
• •PV modules and solar components reliability testing.
• •LED devices and lighting product aging tests.
• •Automotive electronics and sensors.
• •Semiconductors, connectors, switches, and control modules.
• •Plastics, rubber, coatings, adhesives, and packaging materials.
• •Insulation resistance and moisture resistance evaluation.
• •Quality inspection and incoming material validation.

  
  

The chamber helps engineering teams screen early failures and compare product designs, materials, or suppliers under repeatable 85/85 conditions.

The chamber uses a programmable control system to maintain stable 85°C / 85%RH conditions and support repeatable test operation. Users can set constant damp heat programs or customized temperature humidity profiles according to the test method.

Control features:

• •Programmable touchscreen controller.
• •Constant 85°C / 85%RH damp heat mode.
• •Multi-step temperature and humidity profile setting.
• •Optional RS232, RS485, or Ethernet communication.
• •Optional PC monitoring and data recording.
• •Alarm protection for abnormal operation.
• •Multi-language interface available by configuration.

Stable control and data recording help laboratories manage long-duration reliability tests more efficiently.

Long-duration double 85 testing requires stable humidification, uniform airflow, and reliable chamber construction. SANWOOD designs the chamber to support temperature and humidity uniformity during extended test cycles.

System highlights:

• •Stable humidification and dehumidification control.
• •Optimized airflow for chamber uniformity.
• •Built-in refrigeration and heating system.
• •Durable inner chamber structure for high-humidity operation.
• •Water supply and drainage configuration depending on model.
• •Modular system design for easier maintenance.
• •Safety alarms for over-temperature, water level, and abnormal operation.

Final configuration should be selected according to chamber volume, sample heat load, test duration, humidity range, and laboratory operating conditions.

The chamber can be configured to support test conditions related to common damp heat and environmental reliability methods, including IEC 60068-2-78 steady-state damp heat, IEC 60068-2-30 damp heat cyclic, IEC 61215 / IEC 61646 photovoltaic module damp heat testing, ISO 16750 automotive environmental testing, and other customer-specific 85°C / 85%RH procedures.

Customization options:

• •Chamber volume and inner dimensions.
• •85°C / 85%RH test configuration.
• •Temperature and humidity range.
• •Sample rack or fixture.
• •Viewing window and cable port.
• •Communication and data recording.
• •Water supply and drainage system.
• •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.
