A multifunctional, fuzzy-supported PID process controller, with permanent performance adjustments and integrated self-diagnosis system, guarantees absolutely reliable temperature control and realistic conditions for perfect environment simulations.

• Temperature range 20 °C (at least 8 °C above ambient) to 50 °C with a display accuracy of 0.1 °C
• Digital CO₂ controller with precise infrared absorption measurement system (NDIR) with automatic zeroing
• Adjustable CO₂ concentration 0.0 - 20.0 %rh
• Automatic gas bottle switchover for interruption-free operation
• Automatic sterilisation programme via the Memmert STERICard for 4 hours at 160 °C. All sensors and fittings can remain installed during sterilisation
• Multiple overtemperature protection: If the electronic heating control should fail, heating is switched off at a fixed level of 3 °C above the setpoint. An adjustable overtemperature controller TWW protection class 3.1 takes over control in case of failure  at a preset temperature. ASF Automatic Safety Function - a unique safety function - for over- and undertemperature automatically following the setpoint in a freely selectable tolerance range. An alarm sound is activated in case of over- /undertemperature, and the heating is switched off in case of overtemperature. In addition a mechanical temperature limiter, TB, switches off heating permanently if the maximum permitted oven temperature is exceeded by approx. 10 °C.
• Adjustable undertemperature alarm
• 2 high-grade platinum temperature sensors Pt 100 in a 4-wire circuit (for stable long-term transmission of measurement signals) communicate with each other and ensure uninterrupted error-free temperature control at constant working temperature
• Weekly timer programmable to the minute
• Simultaneous display of all parameters, such as temperature, CO₂, humidity, weekday and time information
• Visual and acoustic alarm in case of over-/undertemperature and excess/lack of CO₂, if door is opened or if gas bottle is empty
• Alphanumeric text display in different languages (D/UK/E/F/I)
• Function signals for stand-by, operating mode, heating and over/undertemperature
• Internal log memory with 1024kB to save temperature and error states, with timestamp to the minute
• Chip card control including 1 STERICard
• Serial USB-interface and software Celsius to read out the appliance's internal log memory
• Parallel printer interface for printout of log data via an external PCL3-compatible inkjet printer (USB available via converter)
