Product Description
Labotemp Muffle Furnace FMU-19 is an electric laboratory muffle furnace engineered for precise thermal processing, material testing and analytical sample preparation. With a 12 L ceramic-fiber chamber and a temperature range of 100–1200°C, the FMU-19 suits applications such as ashing, sintering, heat treatment and ceramic testing in research, university and industrial quality-control labs. The unit features a micro-computer SX3 programmable temperature controller with 1°C resolution and ±1°C accuracy, an integrated high-precision K-type sensor, and multiple safety protections for reliable, repeatable operation.

Features

• Uniform temperature control via three-side alloy heating (left, right, top)
• Operation up to 1200°C for high-temperature processing
• Ceramic fiber chamber for low heat loss and energy efficiency
• SX3 microprocessor programmable controller: dual display (set/measured), touch-button setting
• High-precision K-type thermocouple for stable measurement
• Rapid heating: time to maximum temperature ≤ 30 minutes
• Safety systems: over-temperature alarm, door safety lock, thermocouple protection
• Electrostatic coated cold-rolled steel exterior for corrosion resistance

Applications

• Material heat treatment: annealing, sintering and thermal processing of metals, ceramics and composites
• Ash content determination for food, polymers, rubber and petroleum samples
• Chemical and elemental analysis: sample preparation and thermal decomposition
