Product Features
- Three Independent Temperature Zones, Temperature Uniformity ±3℃
Three independent temperature control zones (left, center, and right) effectively ensure the length of the constant temperature zone. Heating elements (silicon carbide rods) are arranged around the furnace tube to form a uniform heating field. Furnace temperature uniformity is ±3℃, temperature control accuracy is ±1℃, and the heating rate is adjustable up to 20℃/min. 50-segment programmable temperature control meets the requirements of complex roasting processes.
- Adjustable Tilting Angle 1-30°, Rotation Speed 1-15r/min
The furnace tube tilt angle is adjustable from 1-30 degrees, and the rotation speed is adjustable from 1-15r/min. Flexible combinations of tilt angle and rotation speed allow for precise control of the material’s residence time and throughput speed within the furnace tube, adapting to the roasting process requirements of different nanomaterials.
