Basic equipment. Rapid, precise and energy-saving temperature changes in the range from - 42 to + 190 °C. For controlled material and function tests, as well as ageing tests. The high-performance air fan in working chamber has depending on operation status automatic adaption of fan speed resp. manual adjustment from 10 to 100 %. The programme is stored on power failure. Specifically suited for tests acc. to IEC 60068. The temperature change rate in heating resp. cooling operation is 10 resp. 3 K / min.
