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.
  • Compact size: 256 l.
  • Adaptive, fuzzy-supported, multifunctional, digital microprocessor PID-controller.
  • Autodiagnostic system with fault indication on temperature control.
  • 2 Pt100 sensors Class A in 4-wire-circuit, mutually monitoring and taking over the performance at the same temperature value.
  • Digital 7-day-programme-timer with real time clock, precise min setting.
  • Integrated timer for tempering profiles of up to 40 ramps, each segment adjustable from 1 min up to 999 h.
  • Digital display (LED) of all set parameters, such as temperature, weekdays, time and set-up values.
  • Digital display of set values and actual values of temperature (LED).

  • USB interface including software 'Celsius' for programming and documentation.
  • Chip card control incl. one MEMoryCard XL with 32 kB (up to 40 ramps).
  • Incl. works calibration certificate for - 20 and + 160 °C and for + 30 °C at 60 % rh.
  • Multiple overtemperature protection: with audible and visual alarm.
  • Housing: textured st. steel, door with double locking and 4-point adjustment, heated rear zinc-plated steel, on castors.
  • Interior: st. steel 1.4301 (ASTM 304), hermetically welded, 3-layer-high-tech-insulation.
  • High-performance ring heaters with optimised air circulation.
  • Door heating to avoid condensate.
  • Refrigerator with 2 compressors.
  • Speed-regulated condenser-fan.
  • Cooling agent R449A.

Additionally on CTC256:
  • Electronically controlled active humidification and dehumidification from 10 to 98 % rh.
  • Autodiagnostic system with fault indication additionally on humidity control.
  • Digital display (LED) of humidity value.
  • Humidity supply with distilled water from 2 tanks integrated in unit on telescopic slide with automatic change over.
  • 2 x 10 l tanks as condensate collector on telescopic slide (TTC: 1 x 10 l condensate collector).
