For precise and accurate measurement of temperature.


Since various applications in life involve knowing the exact temperature, so we need these equipments.

For example:

  • If the body temperature varies by only some degrees it can make a big difference on our health.
  • In various situations such as nuclear power plants, factories,etc., slight changes in temperature make a lot of difference.
