However, if you are looking for one that can match some specific features, a second look over the following models might help you decide:

Best Overall: SMARTRO SC62

One of the most accurate thermometers on the market, SMARTRO SC62 can provide an excellent temperature reading, with the extreme values varying between 32°F and 122°F for indoors and 7.6°F and 125.6°F for outdoors.

It features 3 transmission channels and comes with 1 transmitter, allowing you to add two more if you need to monitor multiple locations for more accurate data. The transmission range extends to 200 feet and the data captured by the sensors is transmitted through wireless and displayed on a large LCD.

Editor’s Choice: AcuRite 00592A4

We have appreciated the elegance and simplicity this model has to offer. Equipped with a large LCD screen that uses tall numbers to display the temperature, it allows you to read the data from distance and even during the night, as it features a blue backlight.

Three channels are available for outdoor monitoring and the transmission range is 330 ft. However, it includes only one transmitter, so you will have to purchase the rest if you wish to monitor other locations.

Best Indoor Outdoor Thermometer for the Money: ThermoPro TP65
