Climatic Test Chambers, Memmert
Climatic test chamber CTC / Temperature test chamber TTC

Simulate the perfect atmosphere for climatic and temperature tests, in particular acc. to DIN EN 60068-2-1, 2-2 and 2-3. Provide for unlimited flexibility for controlled material and function tests as well as for ageing tests.

Standard scope of delivery
Ventilation and control:

  • high-performance air fan in working chamber
  • depending on operation status, automatic adaption of fan speed resp. 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 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 minute setting
  • integrated timer for tempering 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, fan speed 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 logging (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 printing logging files, suitable all PCL3-compatible ink-jet printers (USB available via converter, see accessories)
  • USB interface including MEMMERT Software "Celsius" with added functions 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

Additional standard equipment for CTC:

  • active control for humidifying and dehumidifying (10-98% rh) with digital display of relative humidity - resolution of display: 0,5%, setting accuracy: 1%
  • humidity supply with distilled water from two 10-l- tanks integrated in unit on telescopic slide with automatic change over
  • 2 x 10 l tanks as condensate collector, on telescopic slide
  • incl. works calibration certificate for +30°C at 60% rh
