| The temperature of the furnace shell | After long-term use without stopping the furnace, the shell temperature should be less than room temperature + 35 degrees |
| Protection | It adopts an integrated module control unit, with dual-loop control and dual-loop protection, featuring overshoot, undershoot, segment couple, phase loss, overvoltage, overcurrent, over-temperature, current feedback, and soft start protection |
| Control | It adopts closed-loop technology thyristor module trigger control (phase-shift trigger or zero-crossing trigger mode). The output voltage, current or power is continuously adjustable, and it has 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, which can protect the heating elements and ensure control accuracy |
| Touch screen | 7-inch touch screen collective control, which can display real-time voltage, current and power; Chinese menu, which can display temperature, temperature segment number, segment time, remaining time, output power percentage; can store multiple heating process curves, historical curves and data reports |
| Random accessories | Two heating elements, two sets of rods, one crucible tongs and one pair of high-temperature gloves |
| Warranty scope and period | The electric furnace is covered by a one-year free warranty, but the heating elements are not covered by the warranty |
| Precautions | 1. To avoid affecting the service life of the electric furnace, we recommend that the maximum heating rate be less than 15℃/min. (If the heating rises too quickly at high temperatures, the service life of the heating element will be shortened); 2. This lifting furnace has no vacuum sealing structure, so flammable and explosive gases cannot be introduced; 3. After the lifting furnace is used for a period of time, small cracks will appear in the furnace chamber, which is a normal phenomenon and will not affect the use. At the same time, it can be repaired with alumina coating; 4. It is not recommended to introduce corrosive gases. If strong corrosive gases such as S and Na need to be introduced, please inform us in advance, and we will specially treat the furnace chamber; 5. High-temperature solution cannot be leaked to the furnace bottom. The solution can be isolated by using a base plate or alumina powder; 6. The instrument should be placed in a well-ventilated and non-humid place |
