KSL-1700X-W 1700°C Bench-Top Muffle Furnace with 6″x6″x6″ Chamber and 50mm Quartz Observation Window
KSL-1700X-W is designed for laboratory applications requiring precise high-temperature heat treatment with the added capability of real-time sample observation. Its 3.6-liter cubic chamber (150 x 150 x 149 mm) accommodates various sample sizes while allowing direct monitoring through a 50 mm diameter optical-grade quartz window. This feature supports integration with IR cameras or optical devices to observe sample changes during heating cycles.
The furnace achieves temperatures up to 1700°C for short durations (less than one hour) and can operate continuously at 1600°C. It employs four high-quality molybdenum disilicide (MoSi2) heating elements embedded in a chamber insulated with high-purity alumina fiber to optimize energy efficiency. Temperature control is managed by a high-precision SCR controller with PID and auto-tune functions, maintaining ±1°C accuracy and programmable with up to 30 segments for complex ramping, dwelling, and cooling profiles.

Typical Applications
This muffle furnace is suitable for high-temperature sintering, annealing, material testing, ceramic firing, and other thermal processing tasks requiring precise temperature control and sample observation. The quartz window enables monitoring of sample changes without interrupting the heating cycle, beneficial for research and quality control workflows.
Configuration & Operating Notes
The furnace includes the FA-YD518P-AG temperature controller with PID control and programmable segments. Optional upgrades include the Eurotherm 3504 temperature controller compatible with LabVIEW and a laptop/software package for remote and wireless control. Users should wear heat-resistant gloves and heavy-duty protective glasses when operating due to high surface temperatures and viewing through the observation window.
Gas purging systems can be DIY-installed following provided instructions to enable controlled atmosphere processing.
