Webb3. Mechanical Bimetal Thermometer. A mechanical bimetal thermometer is a thermometer that takes advantage of the properties of two metals with different coefficients of expansion. As the name implies, bi means two and metal means metal. When there is a change in temperature, the two metals will expand and begin to warp.
