Description
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 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 open door

  • 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

Humidity Chambers HCP
The Memmert humidity chamber HCP - This climate chamber offers a full range of comfort, reliability and safety. This humidity chamber is ideally suited for environmental testing, environmental simulation, accelerated service life tests and 85/85 tests according to IEC 60068-2-67 and IEC 60068-2-78.The active humidity control is the guarantee for ideal homogeneity of temperature and humidity as well as for short recovery times after opening the door. In combination with heating on all six sides, including heated inner glass door, it also minimises vaporisation in the interior and thus the risk of condensed water dripping onto the test object. An aluminium thermal conductive layer supports optimum temperature distribution and serves as a heat accumulator in case of a temporary power failure.Model variant TwinDISPLAY: ControlCOCKPIT with two colour displaysYou can find a detailed description of the "TwinDISPLAY" model at www.memmert.com
