Heating element

Domestic high-quality resistance wire (optional Kanthal A1 imported resistance wire)

Temperature control

UAV  program temperature control instrument (standard)

1.30 - stage program temperature control intelligent PID adjustment.

2.With over-temperature protection, the electric furnace heating circuit is automatically cut off when the temperature is over-temperature or broken, (when the electric furnace temperature exceeds 1200 degrees or the thermocouple is blown, the AC relay on the main circuit will be automatically disconnected, the main circuit is broken. On, the ON light on the panel is off, the OFF light is on, and the limited protection electric furnace).

3. With 485 communication interface (standard when purchasing software)

4. With power-off protection function, that is, when the power is turned on after the power is turned off, the program does not start from the starting temperature, but the furnace temperature rises from the time of power failure.

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

If you want to get an imported temperature controller, you may have the following choices for replacement with extra fees.

Tube Furnace Materials

1. High-quality and high-purity alumina polycrystalline fiber curing furnace formed by vacuum suction filtration.

2. It is formed by Japanese technology.

3. The spacing and pitch of the resistance wires in the furnace are all arranged according to the best thermal technology in Japan, and the temperature field is simulated by thermal software

Temperature calibration (optional)

Regular temperature calibration of the tube furnace maintains the accuracy and uniformity of the furnace temperature. You can purchase a simple calibration tool from the company to assist you with this work. The complete calibration kit includes a standard thermocouple S-type, temperature calibrator.

Peripheral surface temperature

≤45℃

Open cover protection system

When the furnace cover is opened, the relay will automatically cut off the main power supply, effectively ensuring the safety of the user.

Vacuum system (optional)

1) Generally, the gas in the furnace tube can be pumped out by roughly vacuumizing:TW-1.5A single-stage pump would be fine

2)  The double-stage pump 2XZ-2 vacuum pump can pump the vacuum degree of tube furnace tube to about 10Pa.

3) The VS-0.1 vacuum system can pump the vacuum degree in the tube furnace to 0.1Pa (with resistance vacuum meter display).

4) VS high vacuum system (composed of molecular and mechanical pump) can pump the vacuum degree in the tube furnace to 10-3 Pa.

5) Constant pressure pump (the system can control the pressure in the pipe within - 100.0KPa ~ 100.0KPa).

6)  British (INFICON) capacitance vacuum gauge (measuring range: 3.8x10-5 -1125 Torr, it can detect various gases, including mixed gases, with accurate measurement, good repeatability, and optional anti-corrosion type: PCG554)

Vacuum flange at the bottom

1. In order to increase the pumping rate and achieve higher vacuum requirements. The original hose connector can be replaced with KF-25 interface (VS-0.1 and VS high vacuum system interfaces are both KF25)

2. If used in the air supply system, the original hose connector can be replaced with a Φ6.35mm double ferrule connector.
