Climatic Test Chamber Model CTC 256 and Temperature Test Chamber Model TTC 256


Rapid, precise and energy-saving temperature changes in the range from -42 ºC to +190 ºC, along with fast humidity recovery times, make the Memmert TTC temperature test chamber and the CTC climatic test chamber with humidity unit a perfect duo for controlled material testing, function tests, ageing tests or climate tests on composites, concrete, plastics or electronic components in material technology, the automotive and aerospace industries, and electronics.

To avoid condensation in the interior, the appliance has various heating systems, including low-voltage door frame and seal heating, contacted via door contacts, condensation water outlet pipe heating, and heated glass sheet and glass frame heating if optional glass door is selected.

The temperature is lowered through an integrated cooling unit. The automatic defrosting system for the cooling unit ensures the perfect running of the test chamber at low temperatures and in permanent operation.

The CTC climatic test chamber can in addition lower humidity in the chamber to 10 % rh or increase it to up to 98 % rh. Humidification takes place via a PTC hot steam generator. The amount of steam is controlled by two self-priming tube dosing pumps. Dehumidification takes place through controlled cooling the evaporator temperature below the dew point

Steel grids and silicone plugs to close up the cable feed-through in the right-hand side wall are provided.

Climate Test Chamber CTC 256 with optional laptop PC Control
