1700℃ Precision Vacuum Atmosphere Furnace (CAT#: STEM-GLE-1839-YJL)

1700℃ Precision Vacuum Atmosphere Furnace, model SQFL-1700 is manufactured by Shanghai Jvjing Precision Instrument Manufacturing Co., Ltd. The 1700℃precision vacuum atmosphere furnace is a new product developed and improved by our company. The visual 7-inch large touch screen makes the program setting faster and the equipment operation status more intuitive. This product integrates a heating system, a gas mixing system, and a vacuum system. The internal circulating water cooling system and the monitoring system can be operated with one key of the control button. This machine has comprehensive functions and meets most of the requirements of customers.

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 imported silicon-molybdenum rods, and is plated with different protective coatings according to different operating atmospheres, which greatly improves the service life
The inner furnace chamber is made of high-temperature-resistant alloy material, professional vacuum design, and unique sealing technology to ensure 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 machine has over-temperature alarm and power-off protection function, leakage protection function, safe and reliable operation, ensuring personal safety
The 485 conversion interface is reserved. By connecting with the computer through the optional special software of our company, the functions of remote control, real-time tracking, historical records, output reports and other functions of single or multiple electric furnaces can be realized
