How to Use:

Use the Guardian Thermometer to Capture Food or Medical Refrigerator / Freezer Temperatures.  Record the Salad Bar area or Food Preparation.  See the Min and MAX Temperature Values over a 100 hour window. Measure Ambient Temperature Conditions - ANYWHERE! For safety, it is important to verify the temperature of the refrigerator. Refrigerators should be set to maintain a temperature between 36°F and 46° F (2°C and 8°C). The Guardian Thermometer can be kept in the refrigerator or freezer to monitor the temperature  Our new model TG-300EP has a 6 ft. sensor cable so the Guardian Alarm Thermometer can sit outside the appliance. This can be critical in the event of a power outage. When the power goes back on, if the refrigerator is still 40°F, the food is safe. Items held at temperatures above 45°F for more than 2 hours should be quarantined. Setting the Alarm to ON and the recording interval by the hour will provide valuable information. Be sure refrigerator/freezer doors are closed tightly at all times. Don't open refrigerator/freezer doors more often than necessary and close them as soon as possible.
