This furnace is specifically designed to evaluate the high-temperature oxidation or corrosion resistance of materials. Operating up to 1000°C or higher, it subjects samples to controlled oxidizing atmospheres. The working principle involves precise control of gas composition (air, oxygen, or mixed gases) and temperature while periodically measuring the sample's weight change or examining its surface. Its purpose is to screen and qualify materials like superalloys, coatings, and ceramics for use in aggressive environments, such as in chemical processing plants, power generation, and aerospace applications.
This configuration is suitable when the sample load must fit a 450 x 450 x 450 MM chamber with usable chamber volume of 91.1 litre, approximate power load of 17.9 kW, square 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.

Trutherm manufactures 1200 Degree Celsius (°C) Oxidation Test Furnace 450 x 450 x 450 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.
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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
