You're referring to alcohol or Mercury thermometers used to take person's temperature?
That constriction slows the flow of the alcohol back into the bulb after the thermometer is removed from your mouth (or elsewhere) so the temperature can be read more accurately. Otherwise the indicated temp would begin to decrease as soon as the bulb is moved to a cooler environment.
That why you see the nurse shaking the thermometer down before use, to get all the alcohol back into the bulb so it can re-expand properly before the next use.

Why does a clinical thermometer have a kink?
The kink in a clinical thermometer prevents the mercury from falling back down when the thermometer is removed from the body. It ensures that the highest temperature reached is recorded until it is reset.
Why is kink provided in a clinical thermometer?
The kink in a clinical thermometer prevents the column of mercury from falling back down when the thermometer is removed from the patient's body, allowing for an accurate temperature reading to be taken and read.
Why do lab thermometer not have a kink?
Lab thermometers do not have a kink in the tube because it allows for a continuous and smooth flow of the liquid inside the thermometer, ensuring accurate readings. A kink could create air bubbles or blockages that would affect the movement of the liquid and compromise the thermometer's precision.
Does digital thermometer has kink?
No need for such kink since the maximum temperature sensed could be recorded and can be seen at any time.

How does the kink in a mercury or alcohol work in a clinical thermometer?
The kink in a mercury or alcohol clinical thermometer helps to prevent the mercury or alcohol from flowing back into the bulb once the thermometer is removed from a patient's body. This ensures that the maximum temperature reached during measurement is retained for reading.
What is the Importance of kink in a thermometer?
Kink in a thermometer is important because it serves as a constriction point that prevents the mercury from sliding back down into the bulb once the temperature has been measured. This ensures that the temperature reading remains accurate.
What is the mercury called on a clinical thermometer?
The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
What are some advantages of a clinical thermometer?
The kink at one end of the thermometer will helps us to read the temperature frequently. P. bhanusree Jhonson grammar school, hyd
