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 1000 Degree Celsius (1000°C) Sulfur Determination Furnace 680 × 680 × 880 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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.

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.
