Temperature and humidity are the two most basic of weather variables and all of us are interested in what they are right now. Classic dial thermometers measure temperature by using a bimetallic spring-like coil that is sensitive to heat. One end of the coil is attached to a pointer and as temperature increases, the metal expands and that rotates a pointer higher around a fixed dial. As temperature decreases, the metal contracts and the pointer moves lower. Many of our classic dial thermometers are designed for beauty as well as accuracy. They are made from superior quality materials able to withstand the elements while delivering fashionable decoration for the home, garden, patio or pool. And Some models come with additional smaller dials which may feature humidity and/or barometric pressure.
