About This Product
Fixed to the outside of the glass, this thermometer is read from inside the room through the window. It stands up to 20 mm away from the window so that air can circulate around it, which stops exaggerated readings that heat radiation through the glass may cause. Export supply of the Window Thermometer can be arranged to laboratories and schools in Tajikistan, Poland, Libya, Haiti and Grenada.
