What is the Use of a Digital Thermometer?

The thermometer is the basic tool that is used for measuring temperatures. There are various types of thermometers that are widely used in Laboratories, Diagnostic labs, Dairy Industries, and many other applications.

There has been a great revolution in the field of thermometers. From the earlier mercury-based thermometers, we have arrived at the digital thermometers of today that have a sensor to measure the change in resistance due to heat.

This change in resistance gets converted into a temperature. The main part of a digital thermometer is the thermistor. It senses the temperature and there is an electronic display to show the temperature. Digital thermometers can read a wide range of temperatures based on their type and purpose.

Hospitals, Scientific Industries and Suppliers, laboratories, Food Industries, and many other industries use high-precision digital thermometers to measure the temperature accurately.

What is a thermistor?

A thermistor is a resistor whose resistance value changes with the change in temperature. When the thermistor gets heated, its resistance goes up or down depending on its temperature coefficient. The analog output is supplied to the ADC through the wires and converted into a digital signal. A microcontroller receives it and after further processing, the temperature reading is displayed on the LCD interface to the microcontroller.

Whether it is used in a Pharmaceutical Industry or a bakery, precision is important in a digital thermometer. Nowadays, highly precise thermometers are available in the market.

Digital thermometers can send data directly to a microprocessor. They are simple to operate, affordable, and precise.

What are the Applications of a Digital Thermometer?

Domestic Purpose

• Check the temperature of the water before bathing.
• To check the temperature of food items for cooking.
• To measure the temperature of grill stands, ovens, and other heating appliances.

Laboratory Purpose

• To check the temperature of a solution.
• To check the room temperature or atmospheric temperature to carry out experiments.

Industrial Purpose

• To measure the temperature of the inner and outer surfaces of the walls.
• Food industries use them to monitor the temperature of food items during various stages of preparation. Especially in the baking and cooking industries, they are very useful. By taking the right temperature, it is possible to achieve the desired temperature where the microorganisms do not multiply.
