Model Number

KBF1700\KBF1600

KBF-1700  is the most cost effective bench-top high temperature muffle furnace . The furnace consists of high quality alumina fiber brick and 1800 type MoSi2 heating elements with special design, and furnace temperature is controlled by high precision SCR ( Silicon Controlled Rectifier) digital controller with accuracy +/-1 deg oC and 51 segments programmable up to 1700 oC or 3092 oF.  It is an ideal tool for materials annealing and sintering in your research laboratory.
