This digitally controlled furnace is engineered to reach very high temperatures, often 1200°C or more, with precision. It is used for sintering, ash testing, or high-temperature heat treatments. The working principle utilizes advanced refractory materials and high-temperature heating elements (like silicon carbide) managed by a sophisticated digital controller capable of running extended programs. Its purpose is to provide reliable, hands-off operation for demanding processes in research, quality control, and small-scale production where extreme heat and precise profiles are required.
This configuration is suitable when the sample load must fit a 370 x 370 x 710 MM chamber with usable chamber volume of 97.2 litre, approximate power load of 18.4 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 1400 Degree Celsius (°C) Digital High Temp Furnace 370 x 370 x 710 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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.
