How to Choose the Ideal Thermometer?

We have all been accustomed to using thermometers since childhood. Any time there is an illness in the family, the first thing that you do is check the affected individual’s body temperature using this device. While you would still find the good old mercury-glass thermometer in most traditional households, technology has made huge strides in the world of healthcare and offered us with several advanced thermometer options to choose from. Why spend time comparing options online or in store when you can get all you need right here? We have compiled a list of some of the best thermometers available in India along with a bit about the different types and key features that you should look for while buying one.

Understanding different types of thermometers

Thermometers are essentially of five types (based on ‘how’ you can use them) –





        4.Tympanic (ear)

        5.Axillary (under the arm)

The type of thermometer that you need depends on your personal preference and the age of the patient. For instance, in the case of an infant, a forehead or tympanic thermometer would be a better option compared to an oral or rectal variant – since babies and kids are generally difficult to deal with. Invasive methods like measuring the temperature through the rectum or mouth may get slightly tricky in such cases. Of course, you also get thermometers that are multipurpose. Here’s the complete lowdown on the different kinds of thermometers that are great for measuring temperature:  

  • Mercury glass thermometers


Once the preferred (and perhaps the only) type of thermometer, the mercury glass thermometer is now considered outdated. Used for measuring temperatures orally, rectally or under the arm, these thermometers are difficult to read. Another downside to mercury glass thermometers is the fact that they release mercury (which is toxic) and break easily (since they are made of glass).   

  • Digital thermometers


Electronic thermometers are the norm today since they do not present any of the disadvantages that a mercury glass thermometer does. With digital displays and a strong body, these are easy to read, safe and user-friendly.    

  • Infrared thermometers


As the name suggests, these thermometers use infrared technology to gauge the heat on the surface (or cavity). The biggest advantage of an infrared thermometer is that it generates results very quickly – within a matter of a few seconds. You also get ear and forehead variants of infrared thermometers with easy-to-read display screens.   

  • Basal thermometers


Basal thermometers are specifically used to gauge slight temperature changes in a woman’s body, indicating that ovulation has taken place. They are placed in the rectum or under the tongue and are very sensitive thermometers, although very rarely used at home.

What features should you look for in an ideal thermometer?

With a horde of thermometers available for you to choose from, how can you ensure that you pick the ‘right’ one? Well, there is no such thing as the ‘right’ thermometer, to start with. However, here is a list of must-haves that you should look for: 

  • Convenience

How easy is it to use the thermometer? Take into consideration the fact that you are choosing one for a senior citizen, who might be suffering from impaired vision or shaky hands. In such a case, you need to choose a thermometer that is easy to handle and delivers the temperature readings loud and clear.   

  • Accuracy

An all-important factor while choosing a thermometer is its ability to provide accurate readings. You don’t want to risk it when it comes to dealing with body temperature and the potentially serious consequences it may have. Choose one that is scientifically tested and assures accurate results. 

  • Response time

Gone are the days of playing the waiting game. When we look for instant gratification in all walks of life, why should it be any different when it comes to healthcare? In fact, this is the one area where time is one of the most crucial factors. Pick a thermometer that delivers temperature readings quickly. 

  • Units of measurement

While we Indians are used to Celsius, there might be some of you who want the reading to be provided in Fahrenheit as well. Although this isn’t essential, check if the thermometer you like offers the option of delivering results in both units of measurement. 

  • Safety

As mentioned above, mercury glass thermometers are known to be hazardous as well as brittle. The thermometer you choose should be sturdy, safe to use and ideally come in a plastic case so you can keep it securely when not in use.
