DIAL THERMOMETERS work on principle of bi metal expansion. Scale or range of temperature which DIAL THERMOMETER can measure may very from -200 0 C to 650 0 Centigrade. DIAL THERMOMETER consists of a sharp metal indicator which is fixed on a circular temperature scale. There are two main components , one is a needle and another is a temperature sensor. Few more types of DIAL THERMOMETERS are Liquid type, Gas filled and Va pour tension dial thermometers.

Ltekonline are the manufacturers of Dial Thermometer used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Lab Equipment and Accessories for Engineering Teaching Lab in Universities
