Standard equipment
Ventilation and Control
· additional air circulation in the interior adjustable in 10% steps through controller
· no drying-out of the load caused by the cooling device due to separation of thermal jacket from interior (e.g. biological samples)
· adaptive, fuzzy-supported, multifunctional, digital microprocessor PID-controller
· energy-saving use of CFC-free cooling/heating system (refrigerant R134a)
· highly efficient automatic defrosting system
· autodiagnostic system with fault indication
· 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, for one set value or start of ramp operation
· integrated timer for tempering profiles of up to 40 ramps, each segment adjustable from 1
min. up to 999 hours
· multifunctional programming via menu on 8- digit alphanumeric digital display (language to
be chosen via set-up): tempering profiles of up to 40 ramps time- and set-point dependent operation speed of mechanical internal air circulation in 10% steps from 10% to 100%
· digital display (LED) of all set parameters, such as temperature, weekdays, time, fan speed, ramp segments and set-up values
· resolution of display for set value and actual value 0,1 °C
· long-term logging (ring store) of all relevant data, GLP-conforming as data logger – 1024
· 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
· USB interface including MEMMERT Software
“Celsius” for programming and documentation
· chip card control incl. one MEMoryCard XL with 32 kB (up to 40 ramps)
· incl. works calibration certificate for +10 °C and +37 °C

Multiple Overtemperature Protection
· with audible and visual alarm
· independently working, digitally adjustable electronic microprocessor overtemperature
controller TWW protection class 3.3 maximum value for overtemperature, minimum value for undertemperature
· additional integral over- and undertemperature protection “ASF” (Auto- Safety-Function) automatically following the set value at a preset tolerance range; audible alarm is activated in case of over- or undertemperature, heating is switched off in case of overtemperature, cooling system is switched off in case of undertemperature
· resolution of display and setting accuracy: 0,1°C
· mechanical temperature limiter TB protection class 1 switching the heating off at approx. 10°C above max. oven temperature
