Infrared thermometers do not need to touch a surface to check its temperature. This means there is less chance for cross-contamination and damage to food. - cant check internal temp. Hold the thermometer as close as possible to the food, food package, or equipment without touching it. Do NOT take readings through glass or metal, such as stainless steel or aluminum. A maximum registering thermometer indicates the highest temperature reached during use and is used where temperature readings cannot be continuously observed. It works well for checking final rinse temperatures of dishwashing machines. • Some devices monitor both time and temperature. The time-temperature indicator (TTI) is an example. These tags are attached to packaging by the supplier. A color change appears in the window if the food has been time-temperature abused during shipment or storage. This color change is not reversible , so you know if the food has been abused. Calibrate after: Bumped or dropped Exposed to extreme temps Before deliveries arrive Before each shift Glass thermometers, such as candy thermometers, can be a physical contaminant if they break. They can only be used when enclosed in a shatterproof casing. • When checking the temperature of food, insert the probe into the thickest part of the food, as shown in the photo. This is usually in the center. Also take another reading in a different spot. The temperature may vary in different areas. • Before recording a temperature, wait for the thermometer reading to steady. Wait at least 15 seconds after you insert the stem or the probe into the food When checking food thermometers must be accurate within +-2*F or +-*1C For ait temps: +- 3 *f or +- 1.5*c Calibrate thermometers There are two ways to calibrate a thermometer. The boiling-point method involves adjusting the thermometer to the temperature at which water boils (212˚F [100˚C], depending on your elevation). The ice-point method involves adjusting the thermometer to the temperature at which water freezes (32˚F [0˚C]). • Use crushed ice if you have it. Add tap water until the container is full. Stir the mixture well. • Make sure the sensing area is submerged. Do not let the stem or probe touch the container. Wait 30 seconds or until the indicator stops moving. • To calibrate a bimetallic stemmed thermometer, adjust it by holding the calibration nut with a wrench or other tool. To calibrate a thermocouple or thermistor, follow the manufacturer’s directions CH5 Make specific staff responsible for receiving.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
