The thermal insulation consists of ceramic fiber and low-density refractory bricks. The heating part is made up of spiral-wound KANTHAL-type electric resistors. The characteristic of a gradient kiln is having different firing zones with different temperatures (thermal gradient), which follow the same firing cycle, on samples of the same type. The advantage of this model compared to previous models is first of all to take advantage of modern electronics, to be able to perform faster cycles, and to be able to fire larger samples, less wear of the resistors and consequently less maintenance as well as being more compact and with a new design. 

 The most important features of this model are: 

• possibility of firing samples with a maximum size of 40x80x20 (h) mm

• ithin each of the 6 cells of approximately +/- 2 / 2.5 ° C
• possibility of setting and managing minimum gradients of 10 ° C and maximum of 60 °C between the cells

• management of the cooking cycle entrusted to a PC (with Windows operating system) equipped with a touch screen

• possibility of saving and printing the results obtained in the various cells during the thermal cycles

• simplicity of manipulation and programming of the PC
• predisposition with USB port and ETHERNET port (4.0)

• possibility of carrying out rapid cycles with times of reaching the maximum temperature from a minimum of 20 minutes of 5 hours

• possibility to program the cooling (optional)
