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 420 × 420 × 800 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 420 × 420 × 800 MM chamber with usable chamber volume of 141.1 litre, approximate power load of 21.400 kW, square chamber profile.
