Features:The digital window thermometer from Nature is ideal for measuring the temperature offline and off grid. This thermometer can be easily fixed onto a window pane with a suction cup, and it charges itself with solar energy. Thanks to its built-in sensor, it measures the outdoor temperature accurately. The thermometer is visible from within the home, and it simultaneously displays three exterior temperature measurements: the current temperature, the minimum and the maximum temperatures as recorded since the last reset.
