Digital Thermometer Humidity Meter Kitchen Room Indoor Outdoor Hygrometer

Description:
To make sure you keep a constant temperature you need to get the best data possible. To do this you need to know both the indoor and outdoor temperatures, this digital thermometer lets you do exactly that. If it is hot outside then you know that you need to keep inside slightly cooler and vice versa. You always know whether to put the heating on or not for your ideal constant temperature.

This is also a hygrometer which means it will tell you the moisture content in the air. This again helps to keep a comfortable constant temperature and humidity.

Ideally you want the temperature of inside to be between 18° - 25° and the moisture content to be between 40% - 65%. This thermometer will display a smiling face as long as these parameters are met. If not, the face will no longer be smiling, which is a sign that you need to improve the conditions inside. The face is so you can tell at a glance whether you have the optimum conditions to work or play in.
