Since infrared forehead thermometers are used to measure human body temperature, they should be FDA approved for clinical use. Thus, thermometers used in the meat industry should be calibrated at a cold temperature e.g. Adjusted mode is a compensation for the difference between skin temperature and body core temperature. If prepared from ingredients at ambient temps or from reconstituted food or canned tuna PHF shall be cooled to 41 F or less.. To what temp should the food be cooled to before placed in a refrigerator? • In most applications, a thermometer should be within ±1°F or ±0.5°C when compared to the reference thermometer used for calibration. 1. cool from 135F to 70F in 2 hours and then from 70F to 41F in 4 hours, Once food is chilled to at least 70F, it can be stored on the top shelves in the refrigerator. If a thermometer is ever dropped, you should go ahead and calibrate it.

EXERCISE Put the following in order from 1-3. As a general guideline for good laboratory and manufacturing practices, thermometers should be recertified / verified on an annual basis. accuracy than the device to be calibrated – for example, a thermometer with a rated accuracy of ±0.2°C should be used to calibrate a device with a rated accuracy of ±0.3°C. Traceable to NIST Include a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy and Traceability Should you require an individual Thermometer Calibration Report, factory calibrated thermometers or custom calibration services are available. 3.
