A coated keypad with digital temperature display allows you to make desired temperature changes as needed. This laboratory freezer also has a temperature memory where you can store or set both the minimum and maximum temperatures….

Optimum protection

Fluctuations in temperature or malfunctions? Don’t worry! The acoustic and optical signal informs you at any time of sudden changes in the appliance! In the event of an unintentional door opening, a door opening alarm will also sound after 60 seconds. The monitoring unit remains in operation for approx. 30 hours by means of a rechargeable battery – so you are additionally alerted by the optical and acoustic warning signal in the event of a power failure.
