The muffle furnace LF 9/11-G1 is designed for analytical work with various materials and heat treatment (heating, hardening, firing) in air.

Key Features:

  • ceramic muffle;
  • internal arrangement of heaters (closed muffle);
  • heating from four sides – side walls, vault and under;
  • microprocessor temperature controller with digital indication, providing ease of control and reading of indications (temperature maintenance accuracy ± 10 °С);
  • the door opens up (cold side towards the user);
  • a special hole on the door for an exemplary thermometer;
  • high-quality thermal insulation of the case minimizes heat loss, contributing to the rapid heating of the chamber (the time to reach the maximum temperature is 120 minutes), and also reduces power consumption;
  • the body of the furnace is painted with heat-resistant powder paint;
  • automatic shutdown of heating when the door is opened, as well as in case of overheating, for example, when the thermocouple fails, ensures safe operation of the furnace.

Features of the basic thermostat:

  • simple general purpose controller;
  • bright LED display showing the current and set temperatures with a resolution of 1 °C;
  • a timer with a sound notification that initiates automatic shutdown of heating after a specified time;
  • sound and light alarm, triggered when the current temperature goes beyond the limits of the allowable range of set values.
