Product Overview
Labotemp box-type muffle furnace FMU-03A provides precise, uniform high-temperature performance for laboratory and industrial processes. The 16 L chamber (250 × 400 × 160 mm) supports material testing, ashing, heat treatment and research up to 1000°C (1100°C allowable). The chamber uses monolithic refractory brick and high-purity refractory materials with ceramic fiber insulation for temperature stability and energy efficiency.

Control & Safety
The furnace integrates an intelligent PID temperature controller with self-tuning for accurate regulation (±3°C) and programmable heating cycles. K-type thermocouple provides reliable temperature feedback. Safety systems include over-temperature protection, real-time voltage and current monitoring, thyristor power regulation and a double-layer insulated structure with corrosion-resistant coating for continuous use.
