KSL1700XA1 1700°C Bench-Top Muffle Furnace with 3.6L Chamber and Precision Temperature Controller
KSL1700XA1 is designed for laboratory applications requiring precise high-temperature annealing and sintering up to 1700°C. Its compact 6″x6″x6″ chamber volume of 3.6 liters accommodates a variety of sample sizes while maintaining uniform temperature distribution essential for consistent material processing. This furnace suits research workflows demanding controlled thermal profiles with programmable ramping and dwelling steps.
The furnace operates using four Super 1800 grade molybdenum disilicide (MoSi2) heating elements embedded within a high-purity alumina fiber insulated chamber. This construction ensures rapid heating rates up to 20°C/min (recommended ≤10°C/min) and excellent energy efficiency. Temperature is monitored by a B-type Pt-Rh thermocouple protected by an alumina tube, providing reliable feedback for the YD858 PID temperature controller. The controller supports 30 programmable segments with ramp, hold, and cool steps, maintaining temperature accuracy within ±1°C and includes safety alarms for over-temperature and thermocouple failure.
