5-Piece Mini Indoor Hygrometer Thermometer, Digital LCD Temperature and Humidity Monitor for Home and Office

【Unique Design】 A button on the top of the thermometer turns the device on and off and switches between °C and °F temperature units. It also allows the thermometer to be switched off when not in use to save energy. The simple, clear LCD screen and larger characters make reading measurements easy, even from a distance. It is also equipped with a comfort indicator. 【Reliable Accuracy】 The home thermometer uses a high-precision sensor that updates every 10 seconds to accurately display the current temperature, humidity, and comfort levels. The measurable temperature range is -20℃~60℃ (-4°F~140°F), with a temperature measurement accuracy of ±1℃ and a temperature resolution of 0.1℃. Measurable humidity range: 10%RH~99%RH, humidity measurement accuracy: ±5%RH, humidity resolution: 1%RH. 【Air Comfort Indicator】 The home thermometer features face icons to quickly indicate the air quality (Comfortable/Normal, Comfortable/Uncomfortable) so you can adjust your humidifier or dehumidifier accordingly and ensure you always live in the most comfortable environment. 【Easy to Install】 The digital indoor thermometer is powered by a CR2032 battery (included). Each thermometer/hygrometer also comes with a spare battery, providing extended use. It can be easily placed on a table or shelf, or mounted on a wall using the included wall stickers. Thanks to the built-in magnets, the indoor thermometer can also be attached to metal surfaces.
