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
