Climatic Test Chamber CTC/Temperature Test chamber TTC
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)
- 2 x 10 litre sumps acting as condensate collectors, on telescopic slide mounts
- 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 GLPconforming
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
- incl. works calibration certificate for +30°C at 60% RH
Heating concept:
- high-performance ring heaters with optimised air circulation
- door heating to avoid condensate
Cooling Concept
- twin compressor
- speed adjustable condenser fan
- chlorine-free 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
