KSL-1500X-LD is CE Certified bench-top high-temperature muffle furnace. The furnace consists of high-quality alumina fiber insulation and SiC heating elements. It is controlled by high precision SCR (Silicon Controlled Rectifier) and temperature controller with +/-1 °C accuracy and 30 programmable segments up to 1500 °C. It is an ideal tool for materials annealing and sintering in your research laboratory. SPECIFICATIONS Furnace Structure Double-layer steel structure with air cooling fan to keep the case's temperature below 60°C High-purity alumina fiber insulation for max. energy saving Precision temperature control with +/- 1ºC accuracy Inside Chamber Size 150 x 150 x 150 mm (6" x 6" x 6"), 3.6L Standard Working Temperature 1400° C (continuous) Maximum Working Temperature 1500° C (< 1 hour) Heating Rate 0 ~20 °C/min ( ≤10°C/min recommended ) Temperature Accuracy +/- 1° C Temperature Controller 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 Laptop & software (Optional) Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) Labview Based Temperature Control System (MTS01)enables users to edit temperature profiles, manage heat-treatment recipes, and record, and plot data for MTI furnaces. A wireless remote control provides up to 300 meters of operating range. Thermocouple S-type Heating Element SiC Power AC 208V-240V single phase, 50/60 Hz, 30 A Note: Plug is not included. 30A plug is recommended (NEMA L6-30P). Max. Power 4 KW Optional Ceramic tube (8 mm Dia, Length 150 mm) with flange can be added as a gas inlet port / gas outlet port of the Furnace, at an extra cost of $200.00 each A furnace with Quartz Window - is available for IR measurement . Compliance CE Certified NRTL (UL61010) or CSA certification is available at extra cost. Attention Notes Performance degradation (i.e. furnace can not reach the maximum temperature of 1500°C or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen.
