Products Description
Temperature humidity calibration chamber, also known as "constant temperature and humidity test chamber", is a device used to simulate constant temperature and humidity conditions for testing and testing. It usually consists of a sealed test chamber, heating and cooling system, humidification and dehumidification system, and temperature and humidity control system, and is widely used in electronic parts, auto parts, notebooks and other product industries.
Temperature humidity calibration chamber--reliability test
Humidity calibration chamber is widely used in scientific research, product testing, quality control and other fields. It can simulate various climate conditions, such as high temperature, low temperature, humidity, dryness, etc., to test the performance and stability of materials, products or systems under these conditions. It can better help manufacturers to discover the weaknesses and deficiencies of products under various real environmental conditions in advance, test and provide data and information for improving product design, and ensure that the products can work more stably and reliably in actual use.
Products structure
Temperature Humidity Calibration Chamber is composed of temperature system, humidity system, refrigeration system, heating element, cooling element, controller, observation window, universal wheel and other parts.
