Because clinical thermometer is used to measure the temperature of
body.

A clinical thermometer is a thermometer used to measure human body temperature. It is specifically designed to measure the temperature of the human body and is usually made up of a glass tube with a bulb at one end containing a liquid such as mercury or alcohol.



Range:
Clinical thermometers are designed to measure temperatures in the range of 35°C to 42°C. They are not suitable for measuring temperatures higher than 42°C or lower than 35°C.

Accuracy:
Clinical thermometers are designed to provide accurate readings of the temperature of the human body. However, they are not as accurate when measuring temperatures outside of the normal range of 35°C to 42°C. When measuring high temperatures, the thermometer may not be able to provide an accurate reading, leading to incorrect diagnosis and treatment.

Dangerous:
High temperatures can indicate serious health conditions such as fever, heat stroke, or other conditions that require medical attention. When measuring high temperatures, it is important to use a thermometer that is designed to handle the high temperatures and does not pose a risk of breakage or leakage.

Alternative:
To measure high temperatures, specialized thermometers such as pyrometers, infrared thermometers, or thermal cameras are used. These thermometers are designed to measure high temperatures accurately and safely.


In conclusion, clinical thermometers are not suitable for measuring high temperatures as they are not designed for this purpose and may not provide accurate readings or pose a risk of breakage or leakage. It is important to use specialized thermometers to measure high temperatures accurately and safely.
