Trutherm Testing Furnace models are used for sample heating, ashing, thermal testing, material evaluation and QC procedures with digital control and multiple chamber sizes.
Trutherm manufactures 1400 Degree Celsius (°C) Testing Furnace 430 x 430 x 855 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.
This configuration is suitable when the sample load must fit a 430 x 430 x 855 MM chamber with usable chamber volume of 158.1 litre, approximate power load of 22.4 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.
Equivalent chamber references: 430 x 430 x 855 MM, 43 x 43 x 86 CM and 17 x 17 x 34 INCH.

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.
