Walk-In Constant Temperature and Humidity Environmental Test Chamber
Test chamber composition:
- Heating system: Generally, electric heating tubes are used for heating, and the temperature is controlled by adjusting the power supply voltage.
- Refrigeration system: It is composed of components such as compressors, condensers, and evaporators. The refrigerant circulates to remove heat to reduce the temperature in the chamber.
- Humidification system: Usually a water tank or steam generator is used to generate water vapor (which can be customized) to increase the relative humidity in the test chamber.
- Control system: It consists of an intelligent controller or a computer control system to monitor and adjust the temperature and humidity of the test chamber.
Performance:
- Temperature and humidity range: It can operate stably under a wide range of temperature and humidity conditions to meet different test requirements.
- Temperature fluctuation and uniformity: The temperature fluctuation is small and the temperature uniformity in the box is good.
- Humidity control: The relative humidity control has high accuracy to ensure the accuracy of the test results.
- Easy operation: User-friendly operation interface, simple and easy-to-understand operation process.
- Durability: The structure is strong, the durability is strong, and it can operate without trouble for a long time.
