IEC 60068 Temperature Humidity Test Chamber -70°C to +150°C Environmental Test

The Temperature Humidity Test Chamber is designed for environmental reliability testing of electronic components, electrical products, appliances, plastics, raw materials and other industrial products.

It provides controlled high-temperature, low-temperature and humidity test conditions to evaluate product performance and reliability during storage, transportation and environmental exposure. With a programmable temperature and humidity control system, the chamber can perform both constant and cyclic environmental tests.

The chamber is suitable for applications such as cold testing, dry heat testing, steady-state damp heat testing and cyclic damp heat testing, making it a practical solution for product development, quality control, reliability laboratories and compliance testing.

Applicable Standards

The environmental chamber is designed for testing methods specified in the following IEC 60068 environmental testing standards:

Programmable Environmental Testing

The controller allows users to create complex temperature and humidity profiles for reliability testing.

The system can display:

• Set temperature and actual temperature
• Set humidity and actual humidity
• Current program and segment
• Remaining test time
• Cycle number
• Running accumulated time
• Real-time temperature/humidity curves
• Relay operating status
• Equipment fault information

The programmable system supports repeated test cycles and automatic continuation after power recovery, helping simplify automated environmental testing for laboratories and production quality-control departments.

Refrigeration System

The chamber uses an air-cooled mechanical compression refrigeration system designed for low-temperature environmental testing.

The refrigeration system automatically adjusts cooling capacity according to the programmed test conditions. This helps maintain stable environmental conditions while reducing unnecessary energy consumption during operation.

Heating System

The heating system uses a fin-type stainless-steel electric heater with solid-state control.

The heating and cooling systems work together with the humidity control system to provide controlled temperature cycling and climatic test conditions.

Air Circulation System

The chamber uses stainless-steel long-axis centrifugal fans to circulate conditioned air throughout the working space. The airflow system is designed to promote uniform distribution of temperature and humidity inside the test chamber.
