Overview
Labotemp Muffle Furnace FMU-19 is an electric laboratory muffle furnace engineered for precise thermal processing, materials testing and analytical heating in research, university and industrial quality-control labs. The unit features a 12 L ceramic-fiber chamber, SX3 programmable micro-computer controller (±1°C accuracy, 1°C resolution), high-precision K-type sensor, and an operational range of 100°C to 1200°C, suitable for ashing, sintering, heat treatment and sample preparation for elemental analysis.

Key benefits

• High-temperature capability up to 1200°C for sintering, calcination and advanced materials tests.
• Accurate temperature management via SX3 microprocessor controller and K-type sensor (±1°C, 1°C resolution).
• Improved thermal efficiency from ceramic-fiber insulation and double-layer construction to reduce heat loss.

Features

• Three-side alloy-wire heating (left, right, top) for uniform temperature distribution.
• Ceramic-fiber chamber providing high insulation and energy efficiency.
• SX3 microprocessor temperature controller with dual display (measured & set temperature) and touch-button setting.
• Fast heating system reaching maximum temperature in ≤ 30 minutes.
• High-precision K-type sensor for stable temperature measurement.
• Safety protections: over-temperature alarm, door safety lock and thermocouple protection.
• Electrostatic coated cold-rolled steel exterior for corrosion resistance.
• Optional upgrades: USB interface, air inlet, 5.0-inch color screen, programmable controller with USB data storage.
