Ultra-low Temperature Test Chamber

An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components.


Ultra-low temperature (humid heat) test chambers are widely used in key laboratories and large-scale third-party testing and testing laboratories, involving aviation, aerospace, weapons, ships, automobiles, intelligent manufacturing, new energy, communications, measurement, electronics, railways, electric power, medical and Scientific research institutes and many other key areas of the national economy, temperature and humidity stress detection, temperature screening, reliability testing, performance testing, weather resistance testing, and ultra-low temperature storage of test pieces under ultra-low temperature conditions.




  1. The body of the low-temperature test chamber is processed and formed by CNC machine tools, with a beautiful appearance and a handle without reaction, which is easy to operate.
  2. The inner liner of the box is made of imported stainless steel (SUS304) mirror panel, and the outer liner of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness.
  3. The large observation window is equipped with a lighting lamp to keep the inside of the box bright, and the built-in tempered glass in the heating element is used to clearly observe the situation inside the box at any time.
  4. Equipped with a test hole with a diameter of 50mm, which can be used for external test power lines or signal lines.
