Muffle Furnace

1. The PID temperature controller ensures precise temperature control. It features multi-stage programmable control and automatic operation.
2. The distinctive furnace door design offers excellent sealing, preventing the leakage of high-temperature hot gas, ensuring uniform temperature within the furnace chamber and corrosion resistance.
3. Ceramic fiber board is employed as the heat insulation and preservation material, providing superior heat insulation and maintaining a low surface temperature of the box.
4. It is furnished with an over-temperature protector, door switch controller, surface cooling fan of the box, and abnormal alarm function to guarantee safe operation.
5. Multiple heat dissipation holes are provided for rapid heat dissipation without influencing the service life of the main unit.

Environmental Conditions:
1. Temperature and Humidity: The working environment temperature should range from 0 to 50°C, the relative humidity should be less than 80%, and the atmospheric pressure should be within 86.0 to 106.0 kPa.
2. Absence of Flammable and Explosive Substances: The equipment should be positioned in a dry and well-ventilated location, free of corrosive gases, flammable substances, and explosive materials.
3. Avoidance of Heat Radiation: The box-type resistance furnace should be maintained at a certain distance from surrounding objects to prevent heat radiation. The clearance from the wall should exceed 200mm.
4. Prevention of Conductive Dust from Entering the Equipment: This is to avoid affecting the normal operation of the electrical system.

Precautions:
1. Select the appropriate temperature range and heating elements in accordance with application requirements.
2. Opt for a suitable temperature control system to guarantee temperature stability and uniformity.
3. The power supply of the box-type resistance furnace and the electrical equipment should be inspected to ensure their normal operation.
4. Since the electric furnace may become damp during storage and transportation, it is necessary to conduct oven drying before use. Dry from room temperature to 200°C for 4 hours, and then from 200°C to 600°C for another 4 hours.
5. Protective gloves should be worn during operation. When loading or unloading samples, it is essential to cut off the power supply first to ensure safety.
6. Consider the dimensions of the furnace chamber and the workpieces. Ensure that the furnace chamber can accommodate the required workpieces and leave sufficient space to guarantee uniform heating.
7. The condition of the heating elements should be inspected regularly, and aged or damaged elements should be replaced promptly to ensure the normal operation of the equipment.
8. The exterior and interior of the furnace body should be cleaned regularly to remove dust, dirt, residues, and oxides, maintaining a clean and tidy state.
9. Relevant safety operation procedures should be followed during operation to avoid high-temperature burns and electrical accidents.
