The muffle furnace SNOL-3/11 is designed for analytical work with various materials and heat treatment (heating, hardening, firing) in air up to a temperature of 1150 °C .

The working chamber of the electric furnace is formed by a ceramic muffle with spiral iron-chromium-aluminum wire heaters partially pressed into it. Heating is carried out from three sides – the side walls and the vault.


The temperature of the electric furnace is controlled by a digital microprocessor temperature controller, which makes it possible to carry out the heat treatment mode with high accuracy according to a given program in two sections – with the possibility of setting the duration of heating and holding.
