The practical small thermometer is ideal for checking the temperature indoors: in the living room, bedroom, cellar, car, workshop or garage. The maximum and minimum values are stored and displayed at the touch of a button. The thermometer adheres to metal surfaces with two small magnets on the back. If you want to set up the device, you can use the fold-out stand. Controlling the room temperature is an important factor for a comfortable and healthy living environment and helps to save energy. Lowering the temperature by just one degree reduces heating costs by up to 6 %. The thermometer is powered by a standard AAA battery 1x 1.5 V (not included).
