Application:
The IEC 60068 programmable constant temperature and humidity test chamber is widely used for conducting cold, hot, wet, and dry tests on raw materials and devices such as electronics, electrical engineering products, electrical appliances, plastics, and more. Its primary purpose is to ensure the reliability of products during storage and transportation under alternating high and low temperature as well as wet and hot conditions.
Features:
- Wide Temperature and Humidity Control Range:
- The chamber offers a broad range of temperature and humidity control to meet diverse user requirements.
- Balanced Temperature and Humidity Control:
- It employs a unique balanced control method to create an ideal environment with stable heating and humidification capabilities. This results in high precision and stability in temperature and humidity control.
- Automatic Refrigeration Circuit Selection:
- The automatic control device can start the refrigeration circuit based on the set temperature value. It can initiate cooling directly under high-temperature conditions using a fully enclosed compressor (imported) air-cooled condensing unit.
- Observation Window:
- An observation window on the door allows users to monitor the test status of samples conveniently.
- Continuous Extreme Condition Testing:
- The chamber can perform continuous testing at extreme temperature and humidity points for up to 30 days.
