The Cleaning InstituteA good indoor thermometer can help you monitor the temperature inside your home, as well as other conditions, such as humidity. Our team used our testing experience to help choose the best products for you if you’re searching for a quality product for your home. We’ve based our selections on several criteria, helping us round out our choices to include only those products that truly hold up to the highest standards.
Several testing categories were used to choose the best indoor thermometers on the market. The best thermometers had multiple functions, including the ability to monitor humidity, as well as temperature. Additionally, good displays were important in choosing quality thermometers, as it was important that buyers were able to easily read displays by including features such as backlights and large numbers. One of the final categories was the ability to track data from temperature and humidity readouts over time. All of these categories were taken into account, along with accuracy in temperature and humidity, to find the best quality indoor thermometers currently available.
ThermoPro’s indoor/outdoor thermometer includes a sensor for wireless monitoring of temperature and humidity with this user-friendly device. Plenty of features make for a well-rounded product.
Most notable upside: With the sensor, you have the ability to monitor temperatures up to 200 feet away either indoors or outdoors. ThermoPro allows you to purchase and keep track of up to two additional sensors on the same monitor. The display has a touchscreen, as well as a backlight and large numbers, that are easy to read. This is hands down one of the best displays on the market when it comes to indoor thermometers.
Biggest downsides: It can be a little difficult to find the right buttons on the display, and navigation can be a little complex. During initial setup of the thermometer, it can take a little while for the sensor to sync with the monitor.
This digital indoor thermometer has multiple functions, measuring everything from the temperature to the comfort level of air inside the room. Easy to use and simple to read, it’s a great option.
Most notable upside: An air comfort indicator measures the humidity in the room, indicating whether it is comfortable, dry, or wet. The thermometer features both a tabletop and a magnet-mountable design, making it easy to set up wherever you want it to go. The thermometer clearly displays both high and low temperature and humidity records, which can easily be cleared at the touch of a button.
Biggest downsides: The lack of a backlight means the thermometer cannot be read in the dark or in dim lighting conditions.
This digital thermometer from ThermoPro features a large display that’s simple to use, with a large display, responsive readings, and plenty of mounting of options.
Most notable upside: The 4 inch touchscreen display is easy to use, and with LCD backlighting, you’ll easily be able to see everything, even in dim or dark lighting conditions. The thermometer comes with multiple mounting options, whether you want to keep it on a table, mount it on a wall, or mount it magnetically on a metal surface. Responsive readings include an accurate temperature, as well as an accurate humidity reader that tracks for comfortable, wet, and dry air conditions. Records are kept of all time highs and lows, as well as highs and lows for the past 24 hours.
Biggest downsides: The backlight turns off quickly, which can be an annoyance if you’re trying to read the display in the dark. It can be easy to hit the wrong buttons on the display and alter settings because of the way it’s set up.
When using a thermometer, it’s important to remember that placement can make a big difference in the accuracy of a reading. Placing a thermometer in direct sunlight can change a reading drastically, raising it by several degrees. Even if you’re using a thermometer indoors, it’s a good idea to remember to keep it away from open windows, where it may be in the sun. If you’re going to be using a thermometer in any spaces where it will be quite cold, the accuracy of the batteries can be affected as well. You will probably want to switch to lithium batteries, rather than standard batteries, to be certain you are getting the most accurate readings possible. While a good quality thermometer will last a while on a battery, the accuracy of a reading will be affected once a battery starts to wear down. If you think your thermometer isn’t working as well as it should, try changing the battery out for a new one.
If you aren’t going to be using your thermometer for a while, it’s a good idea to go ahead and remove the battery completely to keep it from wearing down. Keep the thermometer in a safe place. As they can be fragile instruments, you might want to keep the original packaging, or else have a box to keep them in so they aren’t broken when you keep them in storage. Unlike the mercury thermometers of yesteryear, digital thermometers don’t contain toxic or hazardous materials that will harm you if they do break, so do realize that you’re safe if one does become damaged.
