Climatic Test Chamber CTC256/Temperature Test chamber TTC256
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.

Standard equipment
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 R404A
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
Temperature range:
CTC/TTC: without humidity control: from -42°C up to +190°C
CTC: with humidity control: from +10°C up to +95°C
Power supply 400 V, 3ph, N, 50 Hz
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 10L tanks acting as condensate collectors, on telescopic slide mounts
