    Low Temperature Constant Temperature and Humidity Stability Test Chamber

    Overview Products Knowledge Standards Terms
    The low-temperature constant humidity and heat test chamber simulates a constant low-temperature and high-humidity environment by cooling the refrigeration system and humidifying the electric heater. It is used to test the aging resistance, deformation, and other properties of materials under damp and cold conditions. It is commonly used for quality verification of products such as electronic components, coatings, and plastics.
    Selection
    When selecting, ensure the temperature range covers the commonly used interval of -70℃ to 150℃, humidity control accuracy is within ±2%, and the interior is made of corrosion-resistant stainless steel. Determine the capacity based on sample size, confirm the availability of fault protection functions, and compare the energy consumption standards and after-sales response speed of different brands.
