Frequently Asked Questions on Thermometer
- How does a thermometer work?
It has bulb containing mercury which expands and contracts based on the temperature of body.
It has bulb containing mercury which expands and contracts based on the temperature of body.
Mercury is used in thermometers because it has high coefficient of expansion and easily measure temperature due to high boiling point. Where as alcohol cannot measure the high temperatures because of its low boiling point.
-At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit scale are equal or coincide at -40 degrees.
-What is the range of clinical thermometer in Celsius and Fahrenheit?
The range of clinical thermometer is 35°C to 42°C and laboratory thermometer is -10˚C to 110˚C
-What is the kink in thermometer?
The clinical thermometer has a kink near the bulb. When the thermometer is removed from the mouth of the person. The kink prevents the mercury level from falling so that the temperature can be read easily.
-What is the range of laboratory thermometer and clinical thermometer?
A clinical thermometer reads temperature 35°C to 45°C while the range of laboratory thermometer is -10°C to 110°C. while there is no kink in the laboratory thermometer
- What does a thermometer measure?
A thermometer is an instrument that measures temperature of a solid such as food, a liquid such as water, or a gas such as air. It measures in Celsius, Fahrenheit, and Kelvin.

-What is the most accurate thermometer?
Temporal thermometer is considered to be most accurate thermometer to measure human body temperature.
- How to use a temporal thermometer?
Temporal thermometer is considered to be most accurate thermometer to measure human body temperature.
- How to use a temporal thermometer?
Temporal thermometer fever can be measured easily through performing following steps;
Place the sensor head at the center of the forehead. Slowly slide the thermometer across the forehead toward the top of the ear. Keep it in contact with the skin while moving or sliding
Stop when reach the hairline. Read temperature on the display screen.

- How to use non contact infrared thermometer?
An infrared thermometer is best used to measure the temperature of human body. When directed towards forehead, the body temperature of human is recorded through temporal artery temperature. Because fever temporal temperature provide accurate reading. It basically detects energy emitted by the surface as result of infrared waves from thermometer and converts into heat. The intensity of heat is displaced in units such as Celsius or Fahrenheit.
