When the temperature of the multi-layer metal sheet changes, the amount of expansion or contraction of the metal in each layer varies, causing the spiral coil to roll up or loosen. Because one end of the spiral coil is fixed and the other end is connected to a pointer that can rotate freely, the dial is an aluminum oxide printing plate with a clear and beautiful surface. The pointer is internally adjustable. Bimetal thermometers are available in axial, radial, and universal types. On-site temperature display, intuitive, convenient, safe and reliable, with long service life.
