KSL-1200X-M is a muffle furnace that offers a 12" x 12" x 12" high purity fibrous alumina chamber, gas inlet and outlet ports, and a 30 programmable segments temperature controller and UL / MET / CSA Certified electric components. It is the ideal muffle furnace for preparing samples with temperatures up to 1100 °C in research and dental labs with maximum energy saving. 

SPECIFICATIONS

Structure	High-purity fibrous alumina insulation for maximum energy saving. Heating elements on all three sides of the interior chamber for fast heating and enhanced temperature uniformity. Double-layer steel structure with air cooling fan to keep the furnace's exterior safe to touch. The safety interlock will automatically power off the furnace when the door is opened. Built-in vent port (top) to remove undesirable contaminants and moisture and extend the lifespan of the heating elements and furnace.
Power	208~240V AC, Single phase, 50/60 Hz 7.5 kW, 40 A.  Note: A power cord is included without a power plug.  A proper power plug is available via the figure on the left.
Max Operating Temperature	1200 °C continuously
Temperature Stability	±1 °C
Temperature Uniformity	+/- 8 °C @ 1000°C in the center 260 x 260 x 260 mm area
Max. Heating Rate	<20 °C/min
Temperature Controller	A digital temperature controller (Version 858) is included. Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed 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
Temperature controller (optional)	Upgrade a Eurotherm Temperature Controller for better temperature PID control with accuracy +/- 0.1oC
Laptop, software & WiFi Control (Optional)	Brand new laptop with Microsoft Windows 11 for immediate use. LabVIEW-based Based Temperature Control System (MTS03)enables the user to edit temperature profiles, manage heat-treatment recipes, and record and plot data for MTI furnaces. The above features are available upon request at an extra cost. Please contact us for more information.
Gas Fitting & Exhaust	One 1/4" barbed Gas Inlet was installed on the back 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 extra cost.
Application Notes	For longer furnace service life, we recommend the heating rate not to exceed 10 °C /min. The cooling rate shall also not exceed 10 °C /min. This furnace lacks vacuum sealing, and it is not recommended to use toxic or explosive gases in this furnace without the necessary safety controls and supervision.  Small cracks may appear on the surface of the refractory ceramics over extended use. This is a normal occurrence, and the cracks may be repaired with alumina coating. You may order an alumina crucible by clicking the picture below.  Click here to choose a crucible
