The Certified Alarm Thermometer, model 12215, is a dual channel digital thermometer with an internal and an external sensor, minimum/maximum memory, a large, easy-to-read LCD, and high/low alarm settings. 

This digital thermometer has a temperature-buffered sensor enclosed in a bottle of propylene glycol solution, which ensures accurate measurements that are not impacted by rapid temperature fluctuations caused by frequent refrigerator or freezer door openings.

This digital thermometer mimics temperature readings in a medium similar to the common fluids stored in refrigerators and freezers in pharmacies and labs. In addition to pharmaceutical applications, the thermometer may also be used in food applications such as cold-holding display cases, refrigerators, or freezers.
