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. The propylene glycol solution is GRAS (generally recognized as safe) and mimics temperature readings in a medium similar to common fluids stored in food and laboratory refrigerators, freezers and cold display cases.
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. The internal sensor measure ambient air temperature and the external sensor monitors temperature inside freezers, refrigerators, or cold holding display cases. The external sensor has a 3 meter cable and a stainless steel, blunt probe enclosed in a sealed plastic bottle of propylene glycol, a solution that is classified as GRAS (generally recognized as safe). This enclosure prevents false alarms because the measurements of the probe are not impacted by rapid temperature fluctuations caused by frequent door openings that occur during normal use. 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.
