Tubular Atmosphere Furnace
LC-SK
The SK Series Tubular Atmosphere Furnacesarehigh-performance, energy-efficient electric furnacesdeveloped with advanced international technology. Theysupport both vacuum and atmosphere environments, enabling gas protection for experimental materials. Featuring a sealed furnace tube, extended uniform heating zone, and user-friendly operation, they arecategorized into three models based on heating elements:
1200°C Model: Resistance wire heating.
1400°C Model: Silicon carbide (SiC) rod heating.
1700°C Model: Molybdenum disilicide (MoSi2) rod heating.

Features
AI-Powered Intelligent Control
Adopts an AI-powered intelligent adjustment algorithm with no overshoot, self-tuning function, and power-off data protection. Enables heating/cooling control at any slope, supporting operations like jump (cycle), run, pause, and stop.
Equipped with a 30-segment intelligent temperature controller with PID control, achieving a temperature control accuracy of ±1°C.
Over-Temperature Protection
Features an upper temperature limit alarm that automatically cuts off the main circuit when the temperature exceeds the set limit.
Versatile Tube Configurations
Uses high-purity alumina ceramic fiber for the furnace chamber, offering excellent thermal insulation.
Tube materials are selectable by temperature: quartz tube/stainless steel tube/corundum tube; corundum tubes are standard for 1400°C-1700°C models.
KF Flange Seal
Utilizes KF flanges for superior sealing performance and high vacuum integrity.
RS232 Interface (Optional)
Enables computer connectivity for data logging and control.

1. B-type high-temperature double platinum-rhodium (30%~6%) thermocouple:
Measurement accuracy: ±0.5 at 0–600°C, ±0.2 at 600–1700°C.
2. S-type single platinum-rhodium thermocouple: Ensures ±0.2 accuracy across the fullrange.
*Due to the low thermal shock resistance of corundum tubes, heating/cooling rates should be slowed when using furnaces with corundum tube configurations.
