Constant Temperature and Humidity 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.

  1. Suhu : 0℃~100℃ (≤±0.5℃)
  2. Humidity: 40%~90%RH (≤±2%RH)
  3. Volume : 100 Liter, 250 Liter, 500 Liter, 1000 Liter, 2000 Liter



Constant temperature and humidity 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, In many key areas of the national economy, such as medical care and scientific research institutions, temperature and humidity screening, reliability testing, performance testing, weather resistance testing, and constant temperature and humidity storage of test pieces are carried out under constant temperature and humidity conditions.
