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.
Trutherm manufactures 1200 Degree Celsius (1200°C) Sulfur Determination Furnace 405 x 405 x 810 MM Chamber for buyers who search by exact machine type, chamber size and 1200°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.

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.
