The Acu-Rite Indoor & Outdoor Digital Thermometer is a versatile household thermometer that measures both indoor and outdoor temperature, as well as indoor humidity. It features a digital display that shows temperature in both Fahrenheit and Celsius, and humidity in percent RH. The thermometer also records temperature and humidity readings for the past 24 hours and all-time, and trend arrows indicate whether the temperature and humidity are rising or falling. With a removable stand and magnetic backing, you can place the thermometer anywhere you like. The display can be manually cycled through readings or set to auto-cycle at 5-second intervals. The temperature range of the thermometer is from 32 to 122 degrees Fahrenheit.
