The device that is used for the measurement or indication of the temperature or the gradient of the temperature with the use of a variety of different principles is known as a thermometer. Structurally, it consists of a narrow, hermetically sealed glass tube that is marked with the graduations and have a bulb as well at one end that contain mercury or alcohol that extends along the tube as it expands. There are different types of thermometers that are available in the market. Different thermometers are used for different purposes. This is why they are designed in different ways. Whether it is about monitoring the temperature of the room, body temperature, outdoor temperature or whatsoever, different thermometers are used for different purposes, but the function of all these thermometers is same.

Today, in the market more and more thermometers are found for the use firstly without being checked for the traceable accuracy or even for the suitability of the purpose. Yet the accuracy as well as the suitability of the thermometers to their intended applications can actually become the reason between the passing and failing of the health as well as of the safety audit, wasting whole of the industrial process as well as being correct for the very first time. At the time of choosing the thermometer, it is really very important to understand all of its associated applications, temperature management range, accuracy, resolution as well as the maintenance that is required for achieving the repeatable measurements.For More Details
