What are the parts of a mercury thermometer?
The Uses of Mercury in Glass Thermometers The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber.
What is a mercury thermometer called?
Fever Thermometers There are two general types of mercury thermometers that measure body temperature: Oral/rectal/baby thermometers, containing about 0.61 grams of mercury. Basal temperature thermometers (used to track slight changes in body temperature), containing about 2.25 grams of mercury.
What is the function of a mercury in a thermometer?
Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it’s used in a thermometer. It also has a high boiling point which makes it very suitable to measure higher temperatures.
Is mercury thermometer and clinical thermometer same?
A clinical Thermometer is meant for clinical purposes….Thermometers.
| Clinical Thermometer | Laboratory thermometer |
|---|---|
| Used to measure human body temperature | Used to measure temperature in the laboratory |
| It has kink, which prevents immediate backflow of mercury | It does not have a kink |
What is the parts of clinical thermometer?
A medical thermometer/ clinical thermometer is a device that is used to measure the temperature of a body. A glass thermometer consists of; a stem (long part) and bulb (containing a small amount of mercury). Vital signs help detect or monitor a basic health conditions.
What are the components of thermometer?
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale …
What are the parts of clinical thermometer?
clinical thermometer. More precise than the alcohol thermometer, it is used to take the temperature of the human body; it is graduated from 94°F to 108°F.
How is mercury thermometer made?
The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). It consists of a bulb containing mercury attached to a glass tube of narrow diameter; the volume of mercury in the tube is much less than the volume in the bulb.
What are the 3 differences between clinical and laboratory thermometer?
The clinical thermometer is used to measure body temperature, however, laboratory thermometer is not used for the purpose of measuring body temperature. The temperature range of clinical thermometers is 35°C to 42°C and that of laboratory thermometers is -10°C to 110°C.
What is called clinical thermometer?
A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature.
What are the two part of thermometer?
What is the SI unit of temperature?
kelvin
The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. Unusually in the SI, we also define another unit of temperature, called the degree Celsius (°C). Temperature in degrees Celsius is obtained by subtracting 273.15 from the numerical value of the temperature expressed in kelvin.
What are the parts of a clinical thermometer?
What is the size of mercury?
1,516 miMercury / Radius
How do you measure temperature?
How do I take a temperature?
- Clean the tip with cold water and soap, then rinse it.
- Turn the thermometer on.
- Put the tip under your tongue, towards the back of your mouth.
- Close your lips around the thermometer.
- Wait until it beeps or flashes.
- Check the temperature on the display.
What are the main types of thermometers?

- Digital thermometers.
- Ear (or tympanic) thermometers.
- Infared thermometers.
- Strip-type thermometers.
- Mercury thermometers.
