Upgrade to Eurotherm 3000 series
KSL-1700X-KA3 is a bench-top ultra-high temperature muffle furnace built by the components UL recognized with a max. working temperature up to 1750°C. The furnace uses Kanthal Super- HT (1800C grade) MoSi2 heating elements and is controlled by a high precision SCR (Silicon Controlled Rectifier) digital controller with +/-1 °C accuracy and 30 segments that are programmable up to 1750 °C. It is an ideal box furnace for sintering high-purity ceramic materials at high temperatures without element contamination.
