When just cold isn't enough
The Liebherr LGT 4725 Mediline freezer offers more than 450 liters of content with a temperature range of -10 ° C to -45 ° C. The freezing temperature is digitally displayed to an accuracy of 0.1 ° C and the time, date and temperature are recorded exactly every 2 minutes.
Temperature stability IEC 60068-3
All Liebherr laboratory refrigerators and freezers are tested in the modern Liebherr Research & Development center according to the IEC 60068-3 procedure for measuring temperature stability.
Additional temperature control possible.
An opening (Ø 7.6 mm) is provided at the top of the interior, which offers the option of feeding through an external temperature sensor or another measuring connection.
Alarm on demand.
An optical and acoustic temperature alarm warns of an unwanted temperature change of 2K. The alarm limit can be adjusted if necessary.
Extremely accurate temperature.
The laboratory devices with Profi electronics have 1-point calibration for extremely precise temperature control. This allows compensation between the set and the actual interior temperature. The correction value to be set can be changed in steps of 0.1 ° C.
A good memory for temperatures.
The minimum and maximum indoor temperatures are stored and can be read out at any time over a period of 41 days.
The relay contact can be connected to a central logging or alarm system that can alert security personnel or caretaker, for example, outside working hours. Warnings with optical or acoustic alarm are possible.
Audible warning in case of failure.
When the temperature rises above the set value, you will be warned by an acoustic signal.
