Meat thermometers are generally divided into two types:

traditional metal thermometers and modern wireless meat thermometers.

The working principle of traditional metal thermometers based on the difference in thermal expansion of a bimetallic strip. When the temperature changes, the bimetallic strip bends and drives the pointer to indicate the corresponding temperature value2.

Wireless meat thermometers, on the other hand, adopt a design where the probe and the temperature display component are separated. The probe is equipped with a built-in temperature and can be inserted into the meat block for a long time.

It transmits the temperature information to a remote receiver and display screen via a wireless signal transmitter. In this way, can observe the temperature of the meat block in real-time through the display screen from a distance, making it more convenient to master the roasting time and temperature.
