Dial (Bimetal) Thermometers

Dial (bimetal) thermometers are simple to use, robust in design, and reasonably accurate in low and mid-range temperatures. They donā€™t require any power and are used in many different applications such as food and beverage quality control, general lab use, asphalt/concrete testing, and soil and compost testing. Stem lengths range from 5ā€ to 48ā€ and they can be calibrated in the field. The bimetallic element inside a dial thermometer is constructed of two metal strips that are bonded together. The two strips are different metals that have different coefficients of thermal expansion. When the temperature changes, the two strips will...
