KSL1100XS Compact 1100°C Muffle Furnace with 4″x4″x5″ Alumina Chamber and Programmable PID Controller
The KSL1100XS is designed for laboratories requiring precise thermal processing of small samples up to 1100°C, such as material research and dental applications. Its compact footprint and low power consumption make it suitable for integration into glove boxes, enabling sintering or drying under vacuum or controlled atmospheres. The furnace chamber measures 4 inches by 4 inches by 5 inches and is constructed from high-purity fibrous alumina insulation, which reduces power consumption by approximately 30% compared to conventional designs.
This model features a drop-down door design that facilitates safe and convenient sample loading, with an automatic power cut-off when the door is opened to enhance operator safety. Temperature control is managed by a programmable PID controller with auto-tuning and 30 programmable segments, ensuring accurate and repeatable thermal profiles. The controller includes built-in protections against overheating and thermocouple failure, and offers an RS-485 communication port for PC connectivity and multi-furnace management via optional software.
