Designed for melting and processing precious metals like gold, silver, and platinum, this furnace features digital control for accuracy. Operating at high temperatures (e.g., 1100°C), it ensures precise thermal management of valuable materials. The working principle often involves induction or resistance melting in a crucible, with digital settings to achieve the exact melting point and superheat needed for casting. Its purpose is to provide jewelers, refiners, and dental labs with a reliable, efficient tool that maximizes metal yield and consistency while minimizing oxidation loss.

Trutherm manufactures 1200 Degree Celsius (°C) Digital Precious Metal Furnace 625 x 625 x 890 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 625 x 625 x 890 MM chamber with usable chamber volume of 347.7 litre, approximate power load of 30.8 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.
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.
