KSL1500XS Compact 1500°C Muffle Furnace with 1.7L Chamber and Programmable PID Controller
KSL1500XS is designed for precise annealing and sintering tasks in research and dental laboratories where a compact footprint and high temperature capability are essential. Its 1.7-liter chamber with internal dimensions of 4.7 inches cubed accommodates small to medium samples requiring controlled thermal processing up to 1500°C for short durations or continuous operation at 1400°C.
This furnace operates using silicon carbide (SiC) U-shaped heating elements and an S-type thermocouple to ensure accurate temperature measurement and control. The included FA-YD518P-AG programmable temperature controller features PID control with auto-tuning, allowing users to program up to 30 segments with ramp, dwell, and cooling steps. Safety features include over-temperature and thermocouple failure alarms. The furnace housing incorporates a high-quality alumina fiber insulation rated to 1700°C, surrounded by a double-layer steel case with an air cooling fan to maintain external surface temperatures below 55°C during operation.
