Which type of thermometer is used by the students?

The most commonly used clinical thermometers (the ones that you used to check your body temperature) have mercury in it and are hence also called as a Mercury thermometer. The mercury thermometer usually has a range of 35∘c to 42∘c.

Which thermometer is commonly used in experiments at school?

Infrared thermometers measure temperature from a distance, using the infrared radiation emitted by all objects. These so-called non-contact thermometers make a wide variety of temperature measurement and monitoring activities accessible to school-age students.

Do school thermometers have mercury?

Mercury Sources in Schools Liquid mercury is used in instruments that measure temperature (thermometers), pressure (barometers or sphygmomanometers), humidity (hygrometers), vacuum (laboratory manometers), flow (water meters) and air speed (anemometers).

What is used to measure temperature in the classroom?

A thermometer is a device used for measuring temperature.

What are three types of thermometers?

• Tympanic Thermometers (in your ear)
• Rectal Thermometers (in your rectum)
• Temporal Artery or Infrared Thermometers (across your forehead)

What type of thermometer is used in a biology lab?

The way a laboratory thermometer works depends upon its type. They are generally a liquid-in-glass device, a bimetallic strip, an electronic thermistor thermometer, or infrared (IR) device.

Which thermometer is used for scientific purpose?

Answer: Laboratory thermometers are used in research and scientific applications such as monitoring experiments, maintaining a sterile work environment, calibrating other laboratory instruments, and testing materials. The lower fixed point is 196° C and the upper fixed point is 550° C (-321° F to 1022° F).
