This analytical furnace is used to determine the sulfur content in materials like coal, oil, and steel. Operating at high temperatures (around 1000°C), it combusts the sample in an oxygen-rich environment. The working principle involves burning the sample, converting all sulfur to sulfur dioxide (SO2), which is then measured by infrared detection or titration. Its purpose is critical for environmental compliance (monitoring fuel sulfur levels), metallurgical quality control (sulfur weakens steel), and in the petrochemical industry for feedstock analysis.
This configuration is suitable when the sample load must fit a 470 × 880 × 470 MM chamber with usable chamber volume of 194.4 litre, approximate power load of 24.3 kW, rectangular - tall chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
