Buying Guide

Picking a suitable thermometer can be tricky. Here are a few important considerations to check to ensure you pick the best thermometer.

1. Features

In addition to temperature readings, it is good to buy a thermometer that offers other features and functionalities. It is best if your thermometer has an LCD-display, fever alarm, one-touch use, storing family temperatures, and more such functionalities. Such features are useful when you have to regularly monitor the temperature.

2. Ease of Use

Your thermometer must be easy to use. It is best to pick one that offers one-touch usability. 

3 Accuracy

The most essential trait for any thermometer is that it must deliver accurate results. It is therefore essential to select a high-grade thermometer from a reputed brand. Variations in temperature readings can lead to improper results. Hence, pick a high precision thermometer only.

4. Response Time

Some thermometers deliver results in just one second. Such thermometers are quite handy when it comes to monitoring infants and small kids.

5. No Body Contact

If you will be using one thermometer for the entire family, it is best to pick one that measures temperature without any contact with the body. This prevents pass of infection from one person to the other.

6. Safety

Few thermometer models come with protective probe covers, case covers, and other safety accessories, which may be a choking hazard for kids. If you are buying a thermometer for kids or infants, it must be free from small parts.

7. Cleaning and Maintenance

Thermometers that need less maintenance and offers lasting performance are better than those that need regular cleaning and maintenance. For this reason, a large number of people prefer buying infrared thermometers. It’s also a good practice to use nitrile medical gloves to further reduce the risk of any infection.


Q. What is the best way to use a thermometer?

A. Your thermometer may either come with a mercury tip or monitors temperature from a distance. The best way to measure temperature using a thermometer is to place it on or close to the forehead or ear depending on the model.

Q. Does high body temperature is a serious warning sign?

A. If a patient is suffering from high body temperature for more than two days, it becomes essential to seek medical assistance fast. Yes, continuous high temperature is a warning sign.

Q. Is it worth buying an expensive thermometer?

A. You must buy a thermometer depending on your budget. However, a low-grade or budgeted thermometer may not offer features, functionalities, and ease of use as that offered by an expensive one. If your budget allows, it is best to purchase an expensive thermometer, which is usually, a one-time cost.


Infrared or contactless thermometers are the most expensive ones. They allow measuring body temperature from a distance. Though buying an expensive thermometer can be a big deal initially, but they require less maintenance and cleaning. Also, if you want a multipurpose thermometer, you must purchase one that can measure the temperature of the human body and objects.
