More of a tool, this device is not meant to be used on humans, but instead objects and surfaces. This unit is designed to take readings of HVAC vents, engine blocks, or even cooking gear. It’s an excellent way to detect whether or not a cooling system is working, or how hot a particular surface is. The backlit LCD provides accurate readings, which show up in about one second. The laser is calibrated to one foot away from the sensor, but this thermometer can provide measurements from even further away.

  • Accurate up to 15 inches away
  • Uses infrared to detect surface temperatures
  • Not for taking human or body temperatures

Buyer's Guide

A thermometer is an instrument that is used to measure the body temperature of a person, an animal, or an object. Usually, thermometers come with three basic abilities: gauging temperature, displaying the results, and converting the results to your preferred unit, Celcius or Fahrenheit.

Why Should You Have a Thermometer?

Thermometers are not only to be found in hospitals and clinics. There are quite a few good reasons to have one on hand.

Regular body temperature measurement

A high or low body temperature is a sign that you are falling ill, and to confirm what your temperature levels are, you need a thermometer. It is said that body temperature should be taken twice a day to ensure that all is fine with your health. This check is especially important with babies or little kids who can’t say when they feel ill.

Accurate Measurement

It is common practice to touch your hand to your forehead or neck to tell if you have a temperature, and while this is a good way of knowing if you are running hot or cold, it isn’t a very effective method because it does not give an exact measurement. For this reason, it cannot be relied upon and you need a thermometer to get accurate results.


Owning a thermometer eases you of the worry, stress, and financial strain that comes with having to go to see the doctor every single time you feel feverish.

What are the Types of Digital Thermometers?

There are several different types of thermometers, all performing the same functions in different ways. Generally, thermometers that do not make use of mercury are considered digital thermometers, and here are the three most popular types.


These thermometers are easy to use, quick, accurate, and safe. They are usually placed in the mouth, rectum, or armpit and left for a stipulated period to gauge body temperature. They come with digital displays that give readings in figures and numbers.

Ear (tympanic)

These thermometers carry out temperature measurements inside of the ear canal through infrared technology. They are great because they provide accurate results in a very short time. However, they are not advisable for kids below 6 months because of the size of their ear canals.


These make use of infrared rays to gauge temperatures. Most of the ones that fall under this category are non-contact, making them suitable for use in large crowds and when observing social distancing protocols.

What Should You Look Out for When Getting A Digital Thermometer?


This is literally the most important thing to look out for when shopping for a thermometer. Ensure that you go for one that gives you a precise reading of your temperature, as this helps you to know if there are any abnormalities in your body temperature.


It is important to know what age you are getting a thermometer for and get one that suits you best. While there are thermometers that can be used for all ages, there are ones that are specifically made for particular age ranges; it is generally advisable to shop for the latter. For example, get a pacifier thermometer for your infant rather than one that goes in the ear or mouth.


What temperature measurement unit are you most familiar and comfortable with? You should get a thermometer that displays readings in that unit, or better still, one that can display in multiple units.


While purchasing a thermometer, go for one that can take measurements and display results in a short time. This is especially important with infants or kids who do not have a lot of patience and cannot keep still for a long period.


It is best to get a thermometer that has the memory feature to give you a chance to compare your previous readings and record any improvements.
