Product Description

Product features

Furnace Shell
1. The shell is made of metal Q235 low-carbon steel, with electrostatic anti-corrosion coating on the surface, providing corrosion resistance.
2. The sturdy double-layer metal frame combined with a heat-insulating fan structure results in a low surface temperature of the furnace.
3. Horizontal usage mode, with an upper open cover structure, making operation convenient.
Fire-resistant Materials
Multi-layer heat insulation design, consisting of lightweight alumina ceramic fibers and high-quality heat insulation plates as backing, without asbestos components, with low heat loss and low energy consumption.
Heating System
1. High-quality MoSi2 heating elements, firmly installed on both sides of the furnace chamber, freely radiating heat within the furnace cavity, with a long service life.
2. Two-sided heating (left and right sides), achieving good uniformity within the furnace.
Temperature Control Panel
1. PID combined with SCR control method, with accurate temperature control.
2. International standardized B-type nickel-chromium-silicon thermocouple, with a temperature measurement range of 50-1800°C, long service life.
3. Equipped with a heating indicator light and an alarm buzzer for over-temperature indication.
Program Controller
1. Controller suitable for complex process requirements.
2. Simple and direct operation, flexible programming.
3. Programmable 30 program segments.
4. Over-temperature and fault alarms, automatically protecting.
Vacuum Atmosphere Function
1. With 304 stainless steel sealing flange, achieving vacuum or atmosphere within the furnace tube.
2. High-quality alumina working tube, better cleanliness, preventing contamination of samples.
