A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The most common units of temperature are Celsius, Fahrenheit, and Kelvin.
Thermometeris a simple, inexpensive and long-lasting instrument. They can be easily calibrated by comparing them with a fixed point on the temperature scale or by comparing them with an already calibrated thermometer.
How does the Thermometer work?
Thermometers work by using the physical properties of various substances. For example, liquids and solids expand as they heat up and contract when they cool down. In the same way, gases increase in pressure as they heat up and decrease as they cool down. Using known temperature points of a substance, you can make a thermometer that translates these physical changes into a number that we understand as temperature.
There are various types of thermometers and have many applications in different fields. Some applications of Thermometers are:
- Food Industry
Industrial Thermometer is the only reliable way to know that meat, seafood, egg products and poultry have reached the safe temperature needed to destroy harmful microorganisms. Using Thermometer also prevents wastage of food due to overcooking.
- Beverage Industry
In the beverage industry, temperature plays a vital role in deciding the quality of the final product. During the winemaking or brewing process, the ambient temperature, as well as fermentation temperature, could have a positive or negative effect. Even in the process of milk pasteurization, the temperature is important to ensure the removal of harmful pathogens, such as Escherichia, Salmonella etc.
- Plastic production
Temperature plays an important role in the plastic industry. During the manufacturing stages, several temperature ranges need to be monitored to ensure a high product quality. This can be achieved by using Thermometer.
- Pharmaceutical Industry
It is essential to maintain proper temperature during the manufacturingand storing of medicines. To maintain accurate temperature, one of the most important and simplest tools is the thermometer, and it plays a significant role.
- Metal processing
Be it any type of metal process plant, temperature measurement is always high on the list for operational quality. Temperature measurement and analysis plays a key role in metal processing, as well as monitoring. If the temperature measurement information is not accurate, then it can have an effect on the quality of the final product, as well as cause danger to workplace security.
- Medical Industry
Thermometers allow healthcare professionals to provide accurate diagnosis. Temperature can be measured in various locations on the body which maintain a stable temperature.
Temperature measurement is important to a wide range of activities, including manufacturing, scientific research, medical practice, engineering uses etc. and hence Thermometer is a crucial instrument to many industries.
