GENERAL DESCRIPTION:
M Furnaces have an inner "heat box" surrounded by an air gap set in a steel outer casing.
A vacuum formed, hardened, ceramic fibre shape forms the furnace door surround. A wear-resistant tile forms the sill. The furnace work chamber consists of a muffle of hard wearing sillimanite onto which high quality spiralled wire elements are carefully positioned to produce a uniform hot zone. The M9 furnace chamber (also M7 & M8 on request) is constructed from slab sections with elements embedded in them.
The chamber is surrounded with lightweight insulation for maximum efficiency in typical laboratory usage.
The controls are beneath the chamber and consist of a green illuminating push button on/off switch, an orange "load on" neon, and a red thermal fuse warning neon. PID solid state, fully automatic
temperature controllers are fitted, incorporating thermocouple break protection
as standard.
A choice of PID digital controllers with digital setting and readout are offered. A door safety switch is fitted to all models. Various optional extras are available.
A sheathed thermocouple within the chamber gives accurate temperature sensing. The full width "up and over" door allows
obstruction-free access. The door is counter balanced and below is a full
width, stainless steel work shelf.
