Climatic Test Chamber CTC256

Simulate the perfect atmosphere for climate and temperature tests, specifically in accordance with DIN EN 60068-2-1, 2-2 and 2-3. Provide unlimited flexibility for controlled material and function tests as well as ageing tests.

Ventilation and Control:
  • high-performance air fan in working chamber
  • depending on operation status automatically variable fan speed with manual adjustment from 10 % to 100 %
  • adaptive, fuzzy-supported multifunctional digital microprocessor PID-controller
  • autodiagnostic system with fault indication on temperature and humidity control
  • 2 x Class A, 4-wire circuit, Pt100 sensors, mutually monitoring and maintaining performance at the same temperature value
  • digital 7-day-programme-timer with real time clock, precise minute setting
  • integral timer for heating profiles of up to 40 ramps, each segment adjustable from 1 min. up to 999 hours
  • digital display (LED) of all set parameters, such as temperature, weekdays, time, humidity and set-up values - language to be chosen in setup
  • digital display of set values (resolution: 0.1 °C below 99.9 °C, 0.5 °C above 100 °C) and actual values (resolution: 0.1 °C) of temperature (LED)
  • long-term documenting (ring store) of all relevant data, GLP-conforming as data logger - 1024 kB
  • programme stored on power failure
  • parallel printer interface (incl. real-time clock with date function) for all PCL3-compatible ink-jet printers for GLP-conforming documentation
  • USB interface including Memmert "Celsius" software for programming and documentation
  • chip card control incl. one MEMoryCard XL with 32 kB (up to 40 ramps)
  • incl. works calibration certificate for -20 °C and 160 °C

Heating concept:
  • high-performance ring heaters with optimised air circulation
  • door heating to avoid condensate

Cooling Concept:
  • twin compressor
  • speed adjustable condenser fan
  • refrigerant R449A

Multiple Overtemperature Protection:
  • with audible and visual alarm in case of over-/undertemperature and over-/under-humidity, open door and empty water tank
  • independently working, digitally adjustable electronic overtemperature controller, TWW protection class 3.3
  • additional adjustable Auto-Safety-Function "ASF" for over- and undertemperature automatically following the set value at a preset tolerance range
  • mechanical temperature limiter TB class 1 switching the heating off at approx.10 °C above max. oven temperature

Standards for CTC additionally:
  • Electronically controlled active humidification and dehumidification from 10 % to 98 % rh with digital display of the relative humidity, display resolution 0.5 %, setting accuracy 1 %
  • incl. works calibration certificate for 30 °C at 60 % rh
  • Humidity supply with distilled water from 2 x 10 l tanks on integrated telescopic slide, with automatic water tank change-over
  • 2 x 10 l tanks acting as condensate collectors, on telescopic slide mounts
