These two grades were developed to allow users the choice between a basic model with simpler controls, or an advanced model with more options for programming complex temperature profiles, alarms and logging functions.
But what is the difference between these two types? What functions does each type offer, and how can you choose which is best for you?
The specific abilities of Memmert Singledisplay and Twindisplay models are outlined in the table below;
|Control Cockpit with one TFT-display||Control Cockpit with two TFT-displays|
|Available parameters in the Control cockpit (where available on oven model);
||Available parameters in the Control cockpit (where available on oven model);
|One temperature sensor
PT100 DIN class A in a 4-wire circuit
|Two temperature sensors
PT100 sensors DIN class A in a 4-wire circuit
For mutual monitoring, taking over functions in case of error
|HeatBALANCE function for application specific adjustment of heating power distribution (balance) between the upper and lower heating groups in an adjustment range between -50% and +5-% (does not apply to size 30, HPP110, IPP110plus, ICP and ICH models)|
|Software AtmoCONTROL for data read out and programming of the data logger via Ethernet interface (temporary trial version as free download).
USB pen drive with software AtmoCONTROL available as accessory
|Software AtmoCONTROL on USB pen drive for programming, managing and transferring of profiles via Ethernet interface or USB port.|
|ControlCOCKPIT with USB port for uploading programmes, reading out protocol logs, activating the User-ID function|
|Displaying of already logged protocol data on the ControlCOCKPIT (max 10,000 values correspond to approx. 1 week)|
|Ethernet interface on the rear of the appliance for reading out the protocol log and for online logging||Ethernet interface on the rear of the appliance for reading out the protocol log and for uploading and implementing programmes and for online logging|
|Double overtemperature protection:
Electronic temperature monitoring with freely adjustable monitoring temperature, for models U, I, S with option A6 TWW/TWB (protection class 3.1 or 2), mechanical temperature limiter TB acc. to DIN 12 880
|Multiple overtemperature protection:
Electronic temperature monitoring TWW/TWB (protection class 3.1 or 2 resp. 3.3 for units with active cooling) and mechanical temperature limiter TB (protection class 1) acc. to. DIN 12 880,
AutoSAFETY automatically adjusts to the set value within a freely adjustable tolerance range.
Setting individual MIN / MAX values for over/undertemperature and also for all other parameters such as relative humidity, CO2
|Structured stainless steel housing, rear of zinc-plated steel, ControlCOCKPIT for operation and adjustment of all parameters|
|High-temperature connectors on the rear of the appliance for single-phase power connection according to country specific systems and IEC standards|
|Internal data logger with a storage capacity of at least 10 years|
|German, English, French, Spanish language settings available on the ControlCOCKPIT|
|Digital backwards counter with target time setting, adjustable between 1 minute and 99 days, 23 hours|
|The SetpointWAIT function guarantees that the process time does not start until the set temperature is reached at all measuring points – optional for temperature values recorded by the freely positionable Pt100 sensors inside the chamber|
|Adjustment of three calibration values for temperature and additional appliance specific parameters directly at the ControlCOCKPIT (e. g. relative humidity)|
