Product Overview for 1200C Muffle Furnace
PM L12/12 is a muffle furnace 1200 C with chamber size 300x200x200mm/12″x8″x8″, features the spiral wire coils embedded in alumina fiber insulation with max working temperature up to 1200°C. It is ideal for multiple heat treating applications, such as wax burnout, ashing, heat treating, ceramic and glass seal firing, ignition tests, and heat treating steel parts in labs and industrial.
Main Features
- Tmax 1200 °C
- Dual steel housing with fan cooling for low surface temperature
- The chamber adopts 1500# high aluminum ceramic fiber board, wet vacuum, one body molding
- The bottom of the furnace is made of wear-resistant alumina insulation material
- Fiber-insulated chamber for maximum temperature stability and uniformity
- Embedded heating elements on three sides give an improved temperature gradient
- Programmable muffle furnace with PID temperature controller 32 segments
- SS304 vacuum water cooling sealing flanges with valves and pressure meter included
- Type N thermocouple. Equips two pcs, one for temperature testing, the other for protection
- Open door power off, overtemperature alarm, leakage protection
- CE certified, standard
Safety Measures
- Built-in ammeter and dual voltmeters for easy monitoring and troubleshooting.
- Overheat protection shuts down the furnace if temperature is outside of acceptable range (refer to controller’s manual) or when the thermocouple is broken or malfunctions
- Power failure protection resumes furnace operation right after the point of failure when power is reestablished
- Microprocessor based self-tuning PID control provides optimum thermal process with minimal overshoot
