The main parts of a mercury thermometer are the capillary, the bulb, the scale, and the expansion chamber.
Accordingly, what are the four features of clinical thermometer?
Answer: Sensitivity, Linearity, Responsiveness of clinical thermometers are the same as that of laboratory thermometers. Range: The scale ranges between 35°C to 42°C. This range is centered around the normal body temperature of 36.9°C.
Correspondingly, what are the parts and functions 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 physical properties of clinical thermometer?
A clinical thermometer made up of a long narrow, uniform glass tube. It has a bulb at one end which contains shining liquid mercury. Outside the bulb, a small thread can be seen in which mercury can flow. It has a scale marked from 35°C to 42°C.
What are the three features of a clinical thermometer?
A clinical thermometer consists of a long narrow glass tube. One end of this tube is sealed and the other end has a glass bulb filled with mercury. The temperature scale is marked outside the glass tube of the thermometer. Thermometer should be washed before and after use, preferably with an antiseptic solution.
What are the types of thermometer?
There are different types, but not all thermometers are right for your child.
- Digital thermometers. …
- Ear (or tympanic) thermometers. …
- Infared thermometers. …
- Strip-type thermometers. …
- Mercury thermometers.
What is clinical thermometer with diagram?
: a thermometer for measuring body temperature that has a constriction in the tube above the bulb preventing movement of the column of liquid downward once it has reached its maximum temperature so that it continues to indicate the maximum temperature until the liquid is shaken back down into the bulb.
What is difference between clinical thermometer and laboratory thermometer?
Clinical thermometer is used to measure the human body temperature. A laboratory thermometer is not used for this purpose of measuring body temperature; it is generally used for the measurement of objects which generally have a temperature range outside that of a normal human body.
What is stem in thermometer?
Magnified glass makes up the outside jacket of the thermometer, which is called the stem. A thin bore inside the stem gives mercury a route of travel as it expands and contracts. The thin bore is called a capillary. Magnified glass makes reading the mercury level easier.
What is the difference between clinical and digital thermometer?
The main difference between them is Clinical thermometer works with the help of mercury while Digital Thermometer works with cells. Clinical thermometer is more accurate than digital one when it’s cells are weak.
What is the red part of a thermometer called?
The red liquid is Alcohol, usually Ethanol with a small amount of red dye added. Alcohol is used extensively as a thermometer liquid (similar to Mercury thermometers), esp.
Why mercury is used in clinical 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.
