The rectangular muffle furnace is used in labs to meet the heating requirements. The temperature controller together with a sensor is perfect for trouble-free functioning. At the bottom of the duly inspected and checked muffle furnace is a control panel that contains a digital visualized thermo regulator as well as magnetic thermic for protection system. Double walled thick PCRC sheet which is powder coated is used for making the outer, which is then insulated with high temperature ceramic fiber wool. In the making of heating elements, the wire in the coil form is wrapped on the muffle, fixed firmly with refractory cement and comes with high density ceramic fibre blanket that prevents heat loss. The digital temperature indicator cum controller controls the temperature. The working temperature of the models of maximum temperature 1000 degrees Celsius is 900 degrees Celsius, and the working temperature of the higher with maximum temperature of 1200 degrees Celsius is 1100 degrees Celsius.
