1. Thermometers A device to measure temperatures
Epan needs a thermometer to measure the meat temperature
E. coli in meat can survive at least 160°F temperature
US Dept. of Health & Human Services suggests:
145°F for roasts, steaks, and chops of beef, veal, and lamb;
160°F for pork, ground veal, and ground beef;
165°F for ground poultry;
180°F for whole poultry
To prevent foodborne illnesses

2. Types of Thermometers Liquid-in-glass Thermometers
Bimetal Thermometers
Resistance Thermometers
Infrared Thermometers
Gas Thermometers
Liquid-crystal Thermometers

3. Resistance Thermometer
Resistance thermometers…
Are probes that measures changes in the electrical resistance of metal materials or thermistors. (Thermistors are resisters made of semi-conducting materials.)
The mechanism consists of a metal wire or thermistor housed in a probe such as a slender rod.
Measures up to 1832 Fahrenheit (But we do not need the temp. of the meat to be that high)
