The chamber serves for testing the influence of thermal and climatic effects on tested objects. The instrument is mainly used for obtaining characteristics of objects under test at various temperature and humidity, testing production quality, searching for failures and quality assurance. Dimensions of the test area are 580 x 450 x 750 mm, temperature range for thermal tests is -72 to +180 °C, temperature range for climatic tests (with humidity generation) is +10 to +90 °C. The range of humidity generation is 10 % to 98 %.
