Time：2024-07-03

Here are some maintenance methods for laboratory electric furnaces:

1. Regular cleaning
- After use, wait for the electric furnace to cool down, then wipe the outside of the furnace with a clean damp cloth to remove dust and stains.
- Clean the debris and residue inside the furnace to avoid accumulation that affects the heating effect and contaminates the sample.

2. Check the heating element
- Regularly check whether the connection of the heating element is loose, whether the surface is damaged, oxidized or deformed.
- If damaged, replace the heating element with the same specification in time.

3. Calibrate the temperature sensor
- Calibrate the temperature sensor according to a certain period to ensure the accuracy of the temperature display.

4. Check the control system
- Check whether the buttons and switches on the control panel are working properly and whether the display is clear and accurate.
- Ensure that the control program and parameter settings are correct.

5. Maintain the furnace door and seal
- Keep the furnace door clean and check whether the hinges and handles of the furnace door are flexible.
- Ensure that the furnace door is well sealed. If there are aging or damaged seals, replace them in time.
