1800℃ Muffle Furnace

CE Standard 1800℃ Muffle Furnace
BR-18HM Super high temperature muffle furnace is CE certified muffle furnace which consists of super high quality alumina fiber brick with ZrO2 liner and famous Kanthal Super-1900 MoSi2 heating elements which can be used up to 1800℃. Temperature is controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/-1℃ and 51 segments programmable. It is an ideal tool for materials annealing and sintering in your research laboratory.

Features
1. Operation Temperature: 1700℃ (1800℃ for short time).
2. Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient alumina fiber ceramic insulation.
3. Heavy duty double layer structure with cooling fan. Lower teperature in outside case.
4. PID automatic control via current limiting phase angle fired the resistor, e.g. SCR (Silicon Controlled Rectifier).
5. Power control with 30 segments programmable.
