You are sure to find the right instrument for your laboratory.

Some models feature our TC 2015 touch-screen temperature controller and a special spark resistant PT1000 temperature sensor. For the latter, a safety barrier according to the ATEX guidelines EN 50014 and EN 50020 is installed. In addition to setting the desired temperature, our controller enables the actual value to be read and the temperature curve to be displayed. All stored data including the event log can be exported and archived via a USB connection or ethernet. The intuitive operation of our reliable ATEX freezers also makes it easier for you to document and control the storage of materials. Furthermore, our devices have various alarm messages, for example to draw attention to an open door.
