An indoor-outdoor thermometer allows you to measure temperatures in 2 separate locations – typically indoors and outdoors.

Indoor outdoor thermometers are therefore great for understanding the temperature difference between your home and what the weather and temperature feels like outside.

Some outdoor indoor thermometers come with remote or wireless temperature probes to allow complete freedom on the placement of the second temperature measurement. The primary temperature measurement is taken on the indoor outdoor thermometer display or “base unit” as the thermometer is integrated into the casing.

This thermometer comes with a 1 metre cable meaning the outdoor temperature probe can be placed up to 1 metre away from the indoor outdoor thermometer display unit.

This in/out thermometer is, therefore, best placed on a window sill or close to a doorway where the wired external temperature probe can be passed through the window or door and remain in place whilst the window or door is closed.

Being battery powered the placement of the indoor/outdoor thermometer is extremely flexible and allows for complete freedom and mobility – including moving from season to season if you’re particularly interested in the temperature in certain parts of your home.

It is also possible to use an “indoor outdoor thermometer” to measure the temperature in 2 rooms inside your home.

For instance, measuring the temperature inside your hallway AND inside your child’s bedroom.
