KSL1200XN Programmable 1200°C Muffle Furnace with 19L Chamber and PID Controller
The KSL1200XN is designed for laboratory and research environments requiring precise high-temperature heat treatment within a spacious 19-liter chamber measuring 250mm by 300mm by 250mm. It supports continuous operation up to 1100°C and can reach a maximum temperature of 1200°C for short durations under 30 minutes, making it suitable for a variety of thermal processing tasks such as material sintering, annealing, and sample preparation.
This furnace employs a three-sided integrated Fe-Cr-Al doped Mo heating element arrangement combined with high-purity fibrous alumina insulation to ensure rapid heating rates up to 20°C per minute and excellent temperature uniformity. The double-layer steel casing with an air cooling fan maintains a safe exterior temperature, while safety features include overheat protection, thermocouple break detection, and automatic shutoff when the door is opened. A top-mounted vent port facilitates removal of contaminants and moisture, extending the furnace’s service life.
