This handy thermometer is the ideal tool if a close, precise check of the temperature in refrigerators or freezers has top priority. The digital laboratory refrigerator thermometer works with high-quality sensors to trigger an alarm if the temperature limits are exceeded or are not reached individually. The glass bottle with glysofor filling (included in delivery) reduces the reaction speed of the sensitive cable sensor. This prevents false alarms, e.g. due to the frequent opening of the refrigerator door. You can switch between the display of the refrigerator temperature via cable sensor and the room temperature at the push of a button. The highest and lowest values can also be retrieved.Alternatively, the display can be magnetically attached directly to the exterior of a freezer or a refrigerator, or it can be attached flexibly to many surfaces using the supplied adhesive pads supplied with Velcro fastener. Operation of the thermometer requires a common AAA battery (included).An ISO
