KSL-1200X-J Compact Programmable Muffle Furnace with 150×150×150 mm Heating Area, 100–1200°C Range, and 30-Segment PID Controller
The KSL-1200X-J is engineered for precise thermal processing tasks in laboratory environments requiring controlled heat treatment up to 1200°C. Its compact heating chamber measuring 150 × 150 × 150 mm (4.2 liters) accommodates small batch material testing, sintering, and annealing workflows where space efficiency and temperature accuracy are critical. This furnace is also designed for integration inside compatible gloveboxes, enabling controlled atmosphere experiments.
Temperature regulation is achieved via a digital programmable PID controller featuring 30 programmable segments for ramping, soaking, and cooling profiles. The controller includes auto-tuning, over-temperature and thermocouple failure alarms, and maintains ±1°C accuracy at 1000°C. The furnace construction incorporates high-purity alumina fiber insulation to optimize energy efficiency and a double-layer housing with an integrated cooling fan to reduce external surface temperatures during operation. Additional features include a 1-inch top venting port and rear air inlet to facilitate gas flow or venting as needed.
