LIB Temperature And Humidity Test Chamber is a environmental test chamber that combines temperature and humidity control for environmental testing of products. The compressor of the LIB test chamber can be turned on at 150°C. We specially designed a refrigeration bypass to prevent the compressor damage caused by the excessively high refrigerant temperature in the initial stage of cooling, which greatly improves the stability of the cooling.
1. The low temperature range is wide, and the temperature can be freely selected from -20°C/-40°C/-60°C/-70°C to +150°C.
2. Humidity range can be selected from 10%-98%RH or 20%-98%RH.
3. The temperature and humidity test chamber can be combined with vibration, low air pressure and other environmental conditions. A variety of comprehensive environments can meet the diverse testing requirements of customers.
4. LIB industry has standard products and customized products for the temperature and humidity test chamber. The delivery time of customized temperature humidity control chamber is fast, and engineers will go to the site for installation and training. The equipment is simple and easy to operate.

A temperature and humidity test chamber is a controlled environment chamber that is used to simulate a wide range of temperature and humidity conditions for testing purposes. The working principle of a temperature and humidity test chamber involves the following components and processes:
1. Temperature control system: The temperature control system in the chamber includes a heating element and a cooling system that work together to maintain the desired temperature within the chamber. The temperature is monitored and controlled by a thermostat or temperature controller.
2. Humidity control system: The humidity control system in the chamber includes a humidifier and dehumidifier that work together to maintain the desired humidity level within the chamber. The humidity is monitored and controlled by a hygrometer or humidity controller.
3. Air circulation system: The chamber is equipped with an air circulation system that helps to evenly distribute the temperature and humidity throughout the chamber. This ensures that the testing conditions are consistent across the entire chamber.
4. Control panel: The temperature and humidity settings in the chamber are controlled using a control panel that allows the user to set the desired temperature and humidity levels for the test.
5. Sensors: The chamber is equipped with sensors that monitor the temperature and humidity levels inside the chamber. These sensors provide feedback to the control system, allowing it to adjust the heating, cooling, humidification, and dehumidification systems as needed to maintain the desired testing conditions.
Overall, the working principle of a temperature and humidity test chamber involves maintaining precise control over the temperature and humidity levels inside the chamber to create a controlled environment for testing various products and materials under different environmental conditions.
When choosing a temperature and humidity test chamber, there are several factors to consider to ensure that you select the right one for your specific testing needs. Here are some key factors to consider:
1. Temperature range: Consider the temperature range that the test chamber can achieve and whether it meets the requirements of your testing applications.
2. Humidity range: Similarly, consider the humidity range that the test chamber can achieve and whether it meets the requirements of your testing applications.
3. Size and capacity: Evaluate the size and capacity of the test chamber to ensure that it can accommodate the size and quantity of test samples that you will be testing. Consider the internal dimensions, shelving options, and overall capacity of the chamber.
4. Control and monitoring features: Look for test chambers that offer precise temperature and humidity control, as well as accurate monitoring capabilities. Features such as programmable controllers, data logging, and remote monitoring can be beneficial for ensuring consistent and reliable test results.
5. Compliance and certifications: Ensure that the test chamber meets relevant industry standards and certifications, such as ISO, ASTM, and IEC standards.
6. Budget: Lastly, consider your budget and compare the features and capabilities of different test chambers to find one that offers the best value for your specific testing needs.
By considering these factors and evaluating your testing requirements, you can choose a temperature and humidity test chamber that meets your needs and helps you achieve accurate and reliable test results.
