KSL-1200X-N is a box furnace featuring a 10" x 12" x 10" heating chamber and a 50-segment programmable temperature controller. The furnace is made of UL/MET/CSA certified electrical components and provides a maximum operating temperature of 1200 °C. It is designed for laboratory and research applications to provide reliable thermal performance with optimized energy efficiency. SPECIFICATION Structure High-purity fibrous alumina insulation for maximum energy saving Three-sided integrated heating element provide rapid heating and temperature uniformity within the chamber Double-layer steel structure with air cooling fan to keep furnace's exterior safet to touch Equipped with overheat protection, thermocouple break protection, and an automatic-off function when the door is opened Top-mounted vent port to remove contaminants and moisture to extend furnace service life Power AC220V ± 10%, Single Phase, 50 Hz Power Output: 6.5 KW Operating Temperature Operational Temperature: 0 - 1100 ℃, continuously Max. Heating Temperature: 1200 ℃, < 30min Temperature Stability ±1°C Heating Rate Max. Heating Rate: < 20 °C/min Recommended Heating Rate: 10 °C/min Heating Chamber Chamber Dimension: 250mm x 300mm x 250mm (L x W x H) Notice: Minor cracks of the insulation material may occur after prolonged use. It is normal, repairable, and it does not affect performance. A Heating Element Embeded in Liner is optional upon request, providing low-contamination and corrosion-resistant heating environment Heating Element Fe-Cr-Al doped Mo Thermocouple K-Type Thermocouple Temperature Controller Digital temperature controller is included. Proportional-integral-derivative (PID) control and auto-tune function 50 programmable segments with ramping, cooling, and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm ± 1 ºC temperature control accuracy Default DB9 PC communication port Eurotherm Temperature Controller (Optional) Eurotherm Temperature Controller is available to be upgraded with better temperature PID control ±0.1 ºC temperature accuracy Laptop, software & WiFi Control (Optional) A brand new laptop with Microsoft Windows for immediate use LabVIEW-based Temperature control system enables the user to edit temperature profiles, manage heat-treatment recipes, and record plot data for MTI furnaces Sample Support Shelf (Optional) Quartz Sample Support Shelves are available upon request on an extra cost Allows increased sample loading capacity per heating quartz shelves provide low-contamination and corrosion resistant support surface Gas Fitting & Exhaust One Gas Inlet is installed on the rear panel of the furnace One Gas Exhaust port is built on the top of the furnace casing Compliance CE Certified NRTL (UL61010) or CSA certification is available upon request at an extra cost Application Note This furnace lacks vacuum sealing, and it is not recommended to use toxic and explosive gases in the furnace without safety controls and supervision. Minor cracks may appear on the refractory ceramics over extended use. It is normal and repairable, it can be repaired by alumina coating Alumina crucibles are available upon purchase
