Buttons	Adopts imported metal stainless steel buttons with a service life of over 100,000 times, and comes with LED indicator lights.
Display Parameters	Display parameters: temperature, temperature segment, time period, remaining time, output power percentage, voltage, current, etc.
Temperature Curve Setting	Temperature curve setting: Adopts an intelligent temperature controller, with standard PID, artificial intelligence adjustment PID or MT+ and other adjustment methods. It has self-tuning and self-learning functions, with excellent control characteristics of no overshoot and no underdamping. It has 30-step program control function, which can realize arbitrary slope heating and cooling control. It has programmable/controllable commands such as jump (cycle), run, pause and stop, and allows modification of the program at any time during the program control operation; it adopts an artificial intelligence adjustment algorithm with curve fitting function to obtain a smooth curve control effect.
Control	Adopts closed-loop technology, controllable silicon module trigger control, phase-shift trigger control method. Output voltage, current or power are continuously adjustable, with the characteristics of constant voltage, constant current or constant power; the current loop is the inner loop, and the voltage loop is the outer loop. When the sudden load or no-load current exceeds the limit value, the output current of the regulator is within the rated current range to ensure the normal operation of the output and regulator. At the same time, the voltage loop also participates in regulation, so that the output current of the regulator is within the rated current range. Under the premise of sufficient regulation margin, it maintains the constancy of the output current and voltage; thereby protecting the heating elements from excessive current and voltage impact, achieving safe and reliable control effect and control precision.

STANDARD ACCESSORIES

Standard Accessories

Name		Picture	Quantity	Description
High-temperature Gloves			1 pair	Excellent comfort, keeps hands warm; Cut-resistant, abrasion-resistant, and heat-resistant (withstands contact with 350°C heat for 60 seconds, 100°C heat for 180 seconds). Durable.
Heating Elements	Silicon Carbide Rods		2 pieces	Silicon carbide elements, characterized by their high operating temperature, hardness, and brittleness, are ready for use after formation. For instance, silicon carbide rods and tubes, made from silicon carbide, can achieve a heating temperature of up to 1500°C under dry air conditions. Under vacuum conditions, the operating temperature ranges from 1000°C to 1200°C, while in a nitrogen atmosphere, the long-term use temperature reaches 1350°C.
Heating Elements	Silicon Molybdenum Rods		2 pieces	Silicon molybdenum rods, when heated to high temperatures in an oxidizing atmosphere, form a dense layer of quartz glass on the surface, protecting them from further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. In an oxidizing atmosphere, they can reach temperatures up to 1800°C, making them suitable as heating elements for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractories.
Crucible Tongs			1 piece	1.A common chemical instrument typically used for handling crucibles. Generally made of stainless steel or other non-flammable, oxidation-resistant hard materials. 2.Clean crucible tongs must be used. 3.When using crucible tongs to pick up a hot crucible, the tips should be preheated first to prevent the crucible from cracking due to localized cooling. After use, the tongs should be placed on a table or asbestos mat with the tips facing upward. 4.After the experiment, crucible tongs should be cleaned, dried, and stored in the laboratory equipment cabinet. 5.Use the curved section for gripping crucibles; the tips are for other purposes. 6.Crucible tongs are not necessarily used exclusively with crucibles; they can also be used independently.

Optional Accessories List

Separate Control Cabinet	Touch Screen Instrument	Remote Auxiliary Module
Crucible Hook	Reducer Pipe / Reducing Pipe	Rotating/Tilting Furnace Tube

Safety Protection	1. When using the electric furnace for the first time or after long-term shutdown, baking is required; otherwise, it is easy to cause furnace cracking. 2. Keep clean regularly and check whether the furnace wiring is in good contact. 3. When using the electric furnace, the furnace temperature shall not exceed the rated temperature to avoid damaging the heating elements. It is forbidden to pour various flammable liquids and molten metals into the furnace. 4. During operation, generally below 300℃, the heating rate should not be too fast, because the furnace chamber is cold at the beginning of heating and needs to absorb a lot of heat.
Friendly Tips	1. To ensure the normal service life of the equipment, please do not run at the rated temperature for a long time. 2. Carefully check and verify the quantity of goods and accessories upon receipt to avoid inconvenience caused by missing or incorrect items. 3. To extend the service life of the instrument, we recommend a heating rate and cooling rate of 10℃/min. 4. The cooling rate should not exceed 5℃/min. 5. This furnace has no vacuum sealing structure, so flammable and explosive gases must not be introduced. 6. After this furnace has been used for a period of time, slight cracks may appear in the furnace chamber, which is a normal phenomenon and will not affect usage. At the same time, it can be repaired with alumina coating.
