    Overview Products Knowledge Standards Terms
    The constant temperature test chamber controls the internal temperature through refrigeration and heating systems to simulate a fixed temperature environment. It is used to detect the performance changes of materials under set temperatures, commonly applied in temperature resistance tests for products such as coatings and plastics.
    Selection
    When selecting, consider that the temperature range should cover testing requirements, the chamber volume should match the sample size, temperature fluctuations should be controlled within ±0.5℃, the compressor type should be chosen based on usage frequency, and a safety margin should be reserved to handle extreme testing conditions.
