Difference between Laboratory Thermometer and Clinical Thermometer

A thermometer is a device used to measure temperature. Thermometers are used in a variety of settings, from laboratories to homes. There are two primary types of thermometers: laboratory and clinical. Each type has its own unique benefits and drawbacks. Here is a comparison of the two types of thermometers.

What is Laboratory Thermometer?

Laboratory thermometers are essential tools in any scientific setting. They are used to measure the temperature of a variety of substances, from solids and liquids to gases and even living organisms.

  • Laboratory thermometers are also important for monitoring environmental conditions and for carrying out research at extreme temperatures. There are many different types of laboratory thermometers, each designed for a specific purpose.
  • The most common type is the mercury-in-glass thermometer, which uses a glass tube filled with mercury. The mercury expands as the temperature increases, and the resulting liquid column is used to measure temperature.
  • Laboratory thermometers can also be made from other materials, such as bismuth-in-glass or alcohol-in-glass. These materials have different expansion characteristics than mercury, so they are better suited for certain applications.

Laboratory thermometers are an essential piece of equipment for any scientist or engineer. Without them, much of the work that takes place in laboratories would be impossible.

What is Clinical Thermometer?

Clinical thermometers are specialized instruments used to measure human body temperature. They are usually made of glass and filled with mercury, although digital models are also available.

  • Clinical thermometers are more accurate than regular mercury-in-glass thermometers, making them ideal for use in medical settings. The most common type of clinical thermometer is the oral thermometer, which is designed to be inserted into the mouth under the tongue.
  • Clinical thermometers can also be placed in the armpit, ear, or rectum. Clinical thermometers generally have a larger mercury bulb than other types of mercury-in-glass thermometers, allowing for more accurate readings.
  • Clinical thermometers must be recalibrated regularly to ensure accuracy. Thermometer calibration is a simple process that can usually be done with a screwdriver. Clinical thermometers are an essential tool in any medical setting.

Difference between Laboratory Thermometer and Clinical Thermometer

Laboratory thermometers are designed to measure a wide range of temperatures with a high degree of accuracy. They typically have long, thin stems that allow them to be immersed in liquids, and they are often made from glass or metal. Clinical thermometers, on the other hand, are designed for use on patients.

They usually have shorter stems and can be made from a variety of materials, including plastic, glass, or metal. Clinical thermometers also typically have wider temperature ranges than laboratory thermometers. As a result, they are not as accurate as laboratory thermometers, but they are more convenient for taking quick temperature readings on patients.


The next time you need to take a patient’s temperature, make sure you have the right tool for the job. Knowing the difference between laboratory thermometers and clinical thermometers is essential for getting an accurate reading.
