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 860 x 435 x 435 MM chamber with usable chamber volume of 162.7 litre, approximate power load of 22.7 kW, rectangular - wide 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.

A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
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.
