Have you ever looked up the temperature on your smartphone or watched the local weather forecast and just couldn’t shake the feeling that maybe they’re not getting the temperature in your area right? If that’s the case, then you’ll probably want to find out about buying an indoor-outdoor temperature so that you can track the temperature either in your home or around the outside of the home.

The problem isn’t that modern forecasting is wrong, it’s that they can’t possibly cover the temperature variances over a very large area, so they end up being just too general. One spot might be warmer or colder than another, so it’s up to individual homeowners to find a way to track the temperature in and around their homes themselves. And that’s why we’ve reviewed some of the best indoor outdoor thermometers below.

The Ultimate Guide To Indoor/Outdoor Thermometers

If you’re looking to buy the best indoor outdoor thermometer, judging from the fact that you’re on this page you probably are, then you’ve come to the right place. That’s because we’ve decided that listed the best thermometers wasn’t good enough. We wanted to do a little bit more for our readers, so we’ve decided to write this guide on the subject. In this guide, all of our readers will learn the history of thermometers, but more importantly, they will learn how to buy the best one for their needs.

The History Of Thermometers

Thermometers can be traced back to the beginning of the 16th and 17th centuries. These early thermometers were very simple instruments that trapped air in glass tubes with the open end of them submerged in water reservoirs. In 1610, Galileo improved on this design and used wine in a thermometer instead of water. This created the first alcohol thermometer—although technically, it’s not a thermometer but instead is a thermoscope. The two are similar but different in their operation. While thermometers tell the observer the precise temperature of a certain location, a thermoscope can only tell a person whether the temperature is rising or falling.

It wouldn’t be until 1612 that someone decided to add a numerical scale to the thermoscope. This was an Italian inventor and physiologist Santorio Santorio who used the device to take the temperature of patients. Unfortunately, at this time there was no standard scale established, so these early thermometers varied greatly in their reliability.

In 1654, The Grand Duke Of Tuscany, Ferdinand II, invented the first enclosed thermometer. This early thermometer used alcohol, but unfortunately, because of the lack of a standardized scale, it wasn’t very accurate. It wouldn’t be until the beginning of the 18th century that thermometers would become more reliable thanks to the use of mercury as the liquid measuring the temperature and a more standardized scale.

In 1714, a German physicist Daniel Gabriel Fahrenheit refined Danish astronomers Olaus Roemer’s alcohol-based thermometer.  Instead of using wine as Roemer did, he used mercury and used more refined measurements to measure temperature. In 1724, he would unveil his Fahrenheit scale—a scale that established 32-degrees as the freezing point of water and 180-degrees as the boiling point of water.

Around the same time that Fahrenheit unveiled his new temperature scale, a Swedish astronomer named Anders Celsius released his to the public. This scale, known as the Celsius scale, divided into 100-degrees boiling and freezing parts of water. The first scale he invented had the boiling point of water a 0-degrees and the freezing point at 100-degrees but soon after he flipped it to reverse those points. In 1948, the Celsius scale was adopted by the International Conference On Weights and Measures. It was also adopted as the standard for the scientific community.

How To Buy The Best Indoor Outdoor Thermometer

Now that we know more about the history of the thermometer, it’s time to talk about some of the things that people should look for when they’re buying a new thermometer. Below are some of the things that everyone should consider before they buy a new indoor-outdoor thermometer.

An Easy To Read Display

Probably one of the more important features a person should expect from one of these thermometers is a large easy to read display. If it’s an analog thermometer, then it should feature large easy-to-read numbers and its clear shield should be resistant to fogging. If it’s a digital display, the thermometer should be easy to read from any angle and it also should display nice large numbers.

Temperature Range

Obviously, the most important thing for one of these thermometers to do is accurately measure the temperature. It should display the temperature in both Fahrenheit and Celsius scales—or, at least have the ability to display both. It should feature a minimum indoor temperature range of 32-degrees to 122-degrees and a minimum outdoor temperature of -7.6 degrees Fahrenheit to 125.6-degrees Fahrenheit.

Ability To Measure The Lowest/Highest Temperatures

Although this feature won’t be found on analog thermometers, many of the modern digital thermometers do contain this feature. Having a device that measures the lowest and highest temperature ratings can be extremely helpful to most people—particularly for people operating an amateur weather station.

Ability To Measure Barometric Pressure

This feature is an optional one, but it is one that some people might want to consider looking for. That’s because barometric pressure is extremely important and can alert the observer to upcoming storms.

Wired Or Wireless Display

Something else that the consumer might want to consider is whether they need a wired or wireless display. Although the choice between these two types of thermometers is a personal one, we would like to recommend that people go with a wireless version. These models have a greater range and are easier to install than wired models.

A Clock

A clock is such a basic feature that we hesitated on putting it in this guide, but then we found several indoor-outdoor thermometers that didn’t have this feature, so we thought that we’d better add it. A clock is a helpful feature that can help a person keep track of temperature trends over time and do it without the person having to consult a different clock or watch.
