Types of Thermometers
The below types are classified on the basis of their uses:
- Mercury thermometer: A glass thermometer filled with mercury, which expands and contracts in response to temperature changes.
- Alcohol thermometer: Similar to a mercury thermometer, but filled with alcohol instead of mercury.
- Bimetallic thermometer: A thermometer made of two different metals that expand at different rates, causing the metal strip to bend and indicate temperature changes.
- Digital thermometer: An electronic thermometer that uses a thermistor or thermocouple to measure temperature and display the reading on a digital display.
- Infrared thermometer: A non-contact thermometer that uses infrared radiation to measure the temperature of an object.
- Clinical thermometer: A mercury or digital thermometer used to measure body temperature in medicine.
- Laboratory thermometer: A mercury, alcohol, or digital thermometer used in scientific experiments to measure temperature accurately.
- Industrial thermometer: A thermometer used in industrial settings to monitor temperatures in processes and equipment.
- Soil thermometer: A thermometer used to measure the temperature of the soil.
- Wireless thermometer: A digital thermometer that can transmit temperature readings wirelessly to a remote display or data logger.
- Mouth Thermometers: Mouth thermometers are a type of thermometer used for measuring body temperature. They are typically inserted into the mouth, under the tongue, to get an accurate reading of the body’s internal temperature. Mouth thermometers can be either digital or analog, and they work by sensing the heat generated by the body and converting it into a temperature reading. They are commonly used in homes, clinics, and hospitals for checking the temperature of individuals who are feeling ill.
- Ear Thermometer: An ear thermometer, also known as a tympanic thermometer, is a type of thermometer that measures the temperature inside the ear canal. It uses infrared technology to detect the temperature of the eardrum, which is equivalent to the core body temperature. Ear thermometers are quick, non-invasive, and easy to use, making them a popular choice for measuring body temperature.
The below types are classified on their invention basis:
- Fahrenheit Scale: Daniel Gabriel Fahrenheit
Yes, the Fahrenheit scale is a temperature scale named after its inventor, Daniel Gabriel Fahrenheit. It was first proposed in 1724 and became widely used in the United States. The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F at standard atmospheric pressure. - Centigrade Scale: Anders Celsius
Yes, the Centigrade scale, now known as the Celsius scale, is a temperature scale named after its inventor, Anders Celsius. It was first proposed in 1742 and is now the most widely used temperature scale in the world, especially in scientific and medical applications. The Celsius scale sets the freezing point of water at 0°C and the boiling point at 100°C at standard atmospheric pressure. - Kelvin Scale: Lord Kelvin
Yes, the Kelvin scale is a temperature scale named after its inventor, Lord Kelvin (William Thomson). It was first proposed in 1848 and is now the standard temperature scale in science. The Kelvin scale sets absolute zero, the temperature at which all matter has zero thermal energy, as 0 K. The size of a Kelvin degree is the same as a Celsius degree, but its starting point is shifted to absolute zero. This makes it an absolute temperature scale, as opposed to a relative temperature scale like Fahrenheit or Celsius.
