Product Overview
Labotemp box-type muffle furnace FMU-03A delivers precise and uniform high-temperature performance for laboratory and industrial processes. With a 16 L chamber (250 × 400 × 160 mm) and rated operating temperature up to 1000°C (maximum allowable 1100°C), the FMU-03A is engineered for tasks such as material testing, ashing, heat treatment and research. The chamber uses monolithic refractory brick and high-purity refractory materials combined with lightweight ceramic fiber insulation to ensure temperature stability and energy efficiency. The unit integrates a PID intelligent temperature controller (self-tuning), Type K thermocouple and thyristor power regulation for accurate control (±3°C) and stable heating.

Key Benefits

• Accurate PID temperature control with self-tuning for stable regulation
• Optimized insulation to reduce heat loss and lower energy consumption
• Durable chamber design with corrosion and oxidation resistance for continuous use
• Integrated safety: over-temperature protection plus voltage and current monitoring
• Uniform three-side heating and fast heating rate for reproducible results

Features

• Box-type compact structure with efficient space utilization
• PID intelligent temperature control with high precision (self-tuning)
• Uniform heating from three sides for consistent thermal distribution
• Ceramic fiber and high-purity polycrystalline fiber insulation
• Double-layer insulated body with air gap for thermal safety
• Fast heating rate and stable high-temperature performance
• Integrated electronic control system with real-time voltage and current monitoring
• Thyristor-controlled power regulation for stable output
• Side-opening door for easy sample handling
• Over-temperature protection and safety interlocks
