Product specification

If close, precise temperature monitoring of your fridges or freezers is a top priority for you, this handy thermometer is the ideal tool. This digital thermometer for laboratory refrigerators works with high-quality sensors to sound the alarm if the temperature exceeds or falls below individually specified limits. The glass bottle filled with Glysofor (included) reduces the reaction speed of the sensitive cable sensor. This prevents false alarms, for example if the refrigerator door is opened frequently. At the touch of a button, you can switch between displaying the room temperature and the refrigerator temperature via the cable sensor. You can also retrieve maximum and minimum values.

The display unit can either be magnetically attached directly to the outside of your freezer or refrigerator, or it can be flexibly attached to many surfaces using the Velcro adhesive pads supplied. A standard AAA battery is required to operate the thermometer (included).

An ISO certificate with the measuring points -18°C/+4°C certifies the accuracy of this device.
