What is the difference between a clinical thermometer and laboratory thermometer?

What is the difference between a 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 the difference between clinical and laboratory thermometer give examples?

1- Clinical thermometer are used to measure the temperature of body. Whereas, Laboratory thermometer is not used for the purpose of measuring body temperature. 2- Clinical thermometer temperature range: 35°C to 42°C. Laboratory thermometer temperature range: -10°C to 110°C.

What type of thermometer is used in a lab?

A liquid in glass thermometer is the most commonly used temperature measuring device used in laboratories. This thermometer has a glass bulb attached to a sealed glass tube, known as the stem or capillary tube.

What are the similarities between clinical thermometer and laboratory thermometer?

The similarities between laboratory thermometer and clinical thermometer are:

• Both are made of glass and consist of a long narrow tube made up of glass.
• Both of them have a bulb at one end.
• Both the meters give readings with the mercury that is inside the thermometer.
• Celsius scale is present in both the thermometer.

Why clinical thermometer is not used in laboratory?

Explanation: A clinical thermometer cannot be used to measure high temperatures. A clinical thermometer cannot be used to measure high temperatures because it has been designed to measure only human body temperature which varies over a short range. If it is used to measure high temperatures, it will get damaged.

What is the difference between clinical thermometer and digital thermometer?

A clinical thermometer is for taking body range temperatures, a laboratory thermometer is for use in a lab, with a broad range of temperatures for various applications, A digital thermometer has a digital readout so it is easy to read, almost any thermometer can be digital, clinical and laboratory thermometers can be …

What are the similarities and difference between laboratory and clinical thermometer?

Answer: Similarities Both thermometers are used to measure temperature and both of them use mercury. Differences Clinical thermometer is used to measure human body temperature whereas laboratory thermometer is used to measure temperature of other object which has higher temperature than human body temperature.

Why mercury is used in thermometer?

Mercury is the only one in liquid state at room temperature. It’s used in thermometers because it has high coefficient of expansion. It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn’t stick to the glass surface of glass.

What is clinical thermometer used for?

A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature.

What type of thermometer is always used in biology lab?

What type of thermometer is always used in 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.

What are the similarities and difference between clinical and laboratory thermometer?

A clinical thermometer reads temperature 35°C to 45°C while the range of laboratory thermometer is -10°C to 110°C. The clinical thermometer has a kink near the bulb while there is no kink in the laboratory thermometer.

What is the difference between the capillary tubes of clinical and laboratory thermometer?

Generally, laboratory thermometer has temperature range from − 10°C to 110°C where as clinical thermometer has temperature range from 35°C to 42°C. Usually laboratory thermometer does not have any constriction where as clinical thermometer has the small constriction near the mercury bulb.

Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature.

When was the first clinical thermometer invented?

The first clinical thermometer was invented by Thomas Clifford Allbutt in 1866. As the name suggests, Clinical thermometers are used for clinical purposes, mainly to measure the human body temperature by the doctors. The early clinical thermometers used to be large in size and took a longer time to measure the temperature.

What is the name of the instrument that measures temperature?

Thermometer: Clinical & Laboratory Thermometer. Thermometer (thermos: hot; metron: measure) is the universal instrument used to measure temperature. Temperature and heat are two words which often confuses people.

How to use a thermometer to measure temperature?

Swing or jerk the thermometer so that the mercury is brought back to the glass bulb. Note the temperature difference between two bigger marks on the scale of the thermometer. Let’s say, the difference is of 1 degree. If there are 10 divisions between the two consecutive bigger marks, then one smaller division will be equal to 0.1 oC.
