Constant temperature and humidity cyclic test chamber

The constant damp heat alternating test chamber simulates alternating environments of high temperature and high humidity, as well as low temperature and low humidity, within an enclosed space through heating, humidification, and refrigeration systems. It is used to test the aging resistance, deformation, and performance changes of materials such as coatings and inks under temperature and humidity cycling, commonly applied in product quality verification and research and development testing.
Selection
When selecting, consider that the temperature and humidity range must cover the testing standards, the internal chamber size should match the sample volume, and the temperature change rate should meet experimental requirements. Pay attention to sensor accuracy and uniformity indicators, and confirm that the equipment material is corrosion-resistant. Check the program control functions and data recording methods to ensure they align with daily operational habits.
