When precise, close-range temperature monitoring in refrigerators or freezers is a top priority, this handy thermometer is the ideal tool. The digital laboratory refrigerator thermometer operates with high-quality sensors to alert when individually set temperature limits are exceeded or not met. The glass bottle filled with glycol (included) reduces the response time of the sensitive cable sensor, thus preventing false alarms, for example, from frequent opening of the refrigerator door. With the push of a button, you can switch between displaying the refrigerator temperature via the cable sensor and the room temperature. Additionally, maximum and minimum values can be retrieved. The display can be magnetically attached directly to the outside of the freezer or refrigerator, or it can be flexibly mounted on various surfaces using the included Velcro adhesive pads. A standard AAA battery is required to operate the thermometer (included). An ISO certificate with measurement points of -18 °C/+4 °C confirms the accuracy of the device.
