6. Dial Thermometer
The dial thermometer uses a bimetallic strip wrapped into a coil. One end of the coil is fixed to the
housing of the device and the other drives an indicating needle. The principle behind a bimetallic strip
thermometer relies on the fact that different metals expand at different rates as they warm up. By
bonding two different metals together, the coil bends, causing the needle to move. Bimetallic
thermometers are not as accurate as bulb (mercury or red spirit) thermometers. The dial thermometer
should require no calibration.
