This muffle furnace features digital controls for precise temperature regulation and programming. Operating up to 1000°C or higher, it isolates samples from direct radiant heat and combustion products. The working principle combines the traditional muffle—a ceramic chamber that surrounds the workload—with a digital PID controller for accurate temperature management and complex cycle programming. Its purpose is for high-temperature laboratory applications such as LOI testing, sintering, and heat treatment where contamination must be avoided and repeatability is essential.

Trutherm manufactures 1200 Degree Celsius (1200°C) Digital Muffle Furnace 880 x 650 x 650 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.
This configuration is suitable when the sample load must fit a 880 x 650 x 650 MM chamber with usable chamber volume of 371.8 litre, approximate power load of 31.7 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.
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.
