Heating element

Kanthal A1 imported resistance wire from Sweden (resistance wire can be guaranteed for 2 years)

Control mode

 Use Yudian program temperature control instrument (standard)

1. 30-segment program temperature control intelligent PID adjustment.

2. With over-temperature protection, the electric furnace heating circuit will be automatically cut off when the temperature is over-temperature or when the couple is broken. ON, the ON light on the panel is off, the OFF light is on, and the electric furnace is limitedly protected).

3. With 485 communication interface (standard with optional software)

4. It has a power failure protection function, that is, when the furnace is powered on after the power is turned off, the program does not start from the initial temperature, but starts from the furnace temperature when the power is turned off.

5.The meter has the function of temperature self-tuning

Vacuum seal flange and valve

1. A stainless steel sealing flange and stainless steel needle valve are installed on the top of the furnace body.

2. A plug-in valve, a non-mechanical pressure gauge and a KF-25 vacuum interface are used to connect the vacuum pump at the bottom of the furnace body.

3. Vacuum degree: The vacuum degree of the mechanical pump can reach below 1Pa. If you want to obtain a higher vacuum degree, you can choose a domestic or imported high vacuum unit.

Optional: The following accessories increase vacuum efficiency

4.KF25 stainless steel bellows, KF25 quick remover clamp

5. Optional anti-corrosion digital vacuum gauge with a measurement range of 3.8x10-5 to 1125 Torr. No coefficient conversion is required due to different types of measurement gases.

6. At the top of the flange is installed an electromagnet sample hanging device that can withstand a maximum of 500g. As shown in Figure 1, the sample is hung on the hook through the hanging wire, as shown in Figure 2. Click the control button of the sample hanging device of the electromagnet. The hanging wires fall together into the quenching box, as shown in Figure 3. Before releasing the sample, 5 PSI of argon must be flushed in and the manual flapper valve at the bottom of the furnace tube opened. Pic 4 is the hanging wire

Quenching container

1.A stainless steel box for quenching liquid is fixed at the bottom of the furnace tube

2. A large manual plug valve is installed between the bottom of the furnace tube and the liquid box

Warranty period

One year warranty and lifetime technical support

Special Note:

1. Consumable parts such as heating elements, furnace tubes, sample crucibles, etc. are not included.

2. Damage caused by the use of corrosive gases and acid gases is not covered by the warranty.
