Preparation work when using muffle furnace
lab muffle furnace
      1. When using for the first time or reusing after long-term use, the oven must be oven. The oven time should be room temperature 200℃ for four hours. 200℃ to 600℃ for four hours.

      2. The muffle furnace and the controller must work in a place where the relative humidity does not exceed 85%, and there is no conductive dust, explosive gas or corrosive gas. When metal materials such as grease need to be heated, there are a lot of volatile gas It will affect and corrode the surface of the heating element, destroy it and shorten its life.

      3. The muffle furnace controller should be limited to use within the ambient temperature above 10°C.

      4. According to the technical requirements, regularly check whether the wiring of the electric furnace and the controller is in good condition, whether the pointer of the indicator is stuck and stagnant when moving, and use the potentiometer to calibrate the meter due to magnet, demagnetization, wire expansion, and shrapnel Increased error caused by fatigue, balance failure, etc.

      5. Do not pull out the thermocouple suddenly at high temperature to prevent the jacket from bursting.

      6.Always keep the furnace chamber clean and remove oxides and other things in the furnace in time.
