Versatile Use: Place the thermometer anywhere; it is ideal for wine cellars, greenhouses, kitchens, and more. You can even attach it to walls or magnetic surfaces or stand it upright on tables at three angles. Bluetooth Remote Monitoring: You can keep an eye on your digital hygrometer from anywhere in your home. More Accurate Readings: The indoor thermometer features a built-in Swiss sensor that provides you with more accurate temperature and humidity readings in Celsius and Fahrenheit. It reliably monitors the environment every four seconds, maintaining an accuracy of ± 0.2 °C/± 0.4 °F in temperature from -20 °C to 80 °C (-4 °F to 80 °F) and ± 2 % RH in humidity from 0 to 99 % RH. With an Even Larger Screen: You can now see your data even more clearly with a 3-inch display (7.6 cm), making it easier to use your hygrometer to read temperature data at any time. You can also check if your room conditions meet your custom parameters using vivid symbols on the screen. Exportable Data: You can easily save and export your hygrometer data from the last 68 days with an app to analyze the temperature around you. The app can read the data in real-time and display trends in clear graphs.
