Labotemp Muffle Furnace FMU-24 is an electric muffle furnace designed for reliable high-temperature processing in research laboratories, testing facilities, and industrial applications. With a maximum operating temperature of 1200°C, it is suitable for ashing, calcination, ignition testing, sintering, ceramic and glass firing, heat treatment, and material analysis. The furnace uses embedded HRE alloy heating elements with multi-side heating to promote a uniform thermal environment, while high-alumina ceramic fiber insulation helps reduce heat loss and improve heating efficiency.
Designed as a dependable laboratory furnace and digital muffle oven, the FMU-24 combines programmable PID temperature control with automatic tuning for stable, repeatable thermal processes. Type-N thermocouple monitoring supports accurate temperature feedback, while over-temperature, thermocouple failure, burnout, and power-failure protection enhance operational safety. Durable electrical components and robust insulation support long-term laboratory use, while programmable heating profiles allow users to tailor heating rates and temperature stages to specific processes. This makes the FMU-24 a practical lab muffle furnace for laboratories seeking consistent temperature control, energy-conscious operation, and dependable performance.
