Temperature measuring element

1200°C: K-type thermocouple

1400°C: S-type thermocouple

1600°C and above: Type B thermocouple

Material of heating element

1200°C and 1400°C: Silicon carbide rods

1600°C: Silicon germanium rod

1700°C: 1800-type silicon germanium rod

1800°C: 1850 type silicon germanium rod

Crucible material: 99% quartz ceramic, mullite or 99.9% alumina (three options available)

Installation position of the heating element

1200°C to 1700°C: Around the crucible

1800°C: Two heating systems (10-11 type) are adopted, one on the periphery and the other at the bottom.

Heating rate: Maximum 40°C per minute (nonlinear)

Furnace body structure and material

The structure of the air-cooled double-layer carbon steel furnace features an effective air-cooled guide partition and

 an overall cold air circulation system to prevent high-temperature oxidation of the conductive sheets.

Crucible installation method

1-5L: Flip and insert from the top of the furnace

10-17L: Configure the lift base to enter the high greenhouse

Refractory insulation materials: High-purity alumina lightweight materials, featuring high temperature resistance, 

low heat storage, resistance to sudden temperature changes, and excellent insulation performance.

Furnace shell temperature: Outer shell temperature < 45°C

Safety protection

Integrated module control unit, dual-loop control and protection

Protection functions: overshoot, overshoot, undershoot, segment bias (possibly a typo, it should be "bias"), phase loss, overvoltage,

 overcurrent, over-temperature, current feedback, soft start, etc

Safety temperature control

Closed-loop technology thyristor module trigger control (phase shift or zero-crossing trigger)

The output is adjustable (voltage/current/power), featuring constant voltage, constant current or constant power characteristics

Current inner loop, voltage outer loop, current limiting protection, maintaining constant output, and protecting heat-generating components

Temperature curve setting

Intelligent temperature controller, supporting multiple regulation methods such as PID, artificial intelligence TAPID or MPT

Self-tuning and self-learning functions, no overshoot or undershoot

30-segment program control (supporting arbitrary temperature rise and fall), programmable commands (loop, run, pause, stop), 

and allowing program modification during runtime

Curve fitting algorithm, smooth control effect

Number of segments of the temperature rise curve

50-segment program control, supporting multiple curves (e.g., 1 curve with 50 segments, 2 curves with 25 segments, 3 curves with 15 segments,

 5 curves with 9 segments), can be called freely

Panel buttons: Main power button/knob, heating start button/knob

Random accessories: One crucible tongs, one pair of high-temperature gloves

 Warranty Scope and Period

The electric stove is covered by a one-year free warranty

Ceramic crucibles and heating elements are not covered by warranty
