Double-layer shell structure is adopted, the surface temperature of the furnace body is lower, and the design is compact, which meets the small space requirements of the laboratory
The furnace is made of imported alumina polycrystalline fiber material, which has good thermal insulation performance, durability, high tensile strength, no miscellaneous balls, high purity, and the energy-saving effect is obviously better than that of domestic fiber materials
The heating element adopts Swedish Kanthal high-quality alloy wire, which has the characteristics of high surface load, high resistivity, good oxidation resistance and durability, and the maximum temperature can reach 1200 °C
The inner furnace chamber is made of high-temperature resistant alloy material, professional vacuum design and sealing technology, which ensures the airtightness of the furnace chamber, and the vacuum degree far exceeds that of similar products
Two air inlet ports are reserved, which can control the gas flow separately, equipped with a gas mixing device, and can enter different atmospheres to meet the requirements of the atmosphere experiment
The machine integrates an internal circulating water cooling system to avoid the cumbersome external water source and make the outer surface temperature of the equipment lower
The 485 conversion interface is reserved. By connecting with the computer through the optional special software of our company, functions such as remote control, real-time tracking, historical records, and output reports of a single or multiple electric furnaces can be realized
This machine has over-temperature alarm and power-off protection function, leakage protection function, safe and reliable operation, ensuring personal safety
