9. TFA 31.1049.02.K Professional digital thermometer LT-105 Laboratory thermometer Calibration certificate
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 users when individually set temperature limits are exceeded or not reached. The glass bottle filled with glycol (included) reduces the response time of the sensitive cable sensor, thereby avoiding false alarms, such as those caused by frequent opening of the refrigerator door. With the push of a button, users 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 for the thermometer to operate (included). An ISO certificate with measurement points of -18 °C/+4 °C confirms the accuracy of the device.
