Fever is a sure sign that there’s something wrong in our bodies. It’s not a disease itself, but only signals an irregularity that affects our body functions. Our body warms itself in an attempt to “repair” it. Under normal circumstances, fever doesn’t always signify an emergency, but early intervention will go a long way especially when it a more serious illness that’s emerging.

Equipping yourself with a body or forehead thermometer gets you a head start in early detection. Usually, a thermometer detects fever through the forehead, so some opt for a forehead thermometer for adults that is non-contact. On the other hand, others are more confident in using a contact thermometer as it reads temperatures directly from the body it is in contact with.

Why Do I Need to Own a Thermometer?

Especially now that we are amid the pandemic where a fever could signify the presence of the COVID-19 virus itself or other diseases, a thermometer is a definite must-have for every household. This is the perfect time to invest in a reliable and durable one.

There are a lot of adult and baby body thermometers in the market, and it is challenging to know which one fits your needs. Here are some of the common ones:

Glass or Mercury Thermometer

This is one of the first thermometers to hit the market. It consists of a small glass tube with liquid mercury inside a bulb at the bottom. The liquid mercury tends to rise in the valve when it detects an increase in temperature. That is how you get a reading.

However, mercury thermometers are now obsolete since liquid mercury is dangerous. Since mercury thermometers are made of glass, the risk of breaking it and the liquid mercury coming out getting contact with our skin is very high.

Digital Thermometer

A digital thermometer for adults is the same build as a mercury thermometer, only that it replaces liquid mercury with a digital sensor to read the temperature. A digital thermometer also improves the accuracy of the reading since it is electronic. It is also made of plastic material with a probe that has sensors. It has an LCD that displays the temperature reading.

Infrared Thermometer

Aside from incorporating sensors, using infrared frequency also improves the accuracy and speed of reading temperature results for this forehead thermometer. An infrared thermometer is also non-contact, so it is more hygienic to use than its other digital counterparts.
