25 test tube samples can be sintered simultaneously under vacuum and atmosphere. The PID parameter self-tuning function, manual/automatic non-interference switching function, over temperature alarm function, and temperature compensation and correction function all ensure the accuracy and stability of temperature.

   Equipment features:
1. Stable and reliable control, convenient operation.
2. 25 test tube samples can be sintered simultaneously under vacuum and atmosphere.
3. Setting up an electric lifting mechanism can achieve cyclic temperature rise and fall treatment of samples inside the test tube.
4. After lifting the sample, it can achieve automatic and rapid air cooling;
5. Adopting advanced PID self-learning fuzzy control, the temperature control accuracy is high and maintained at ± 1 ℃.
6. The furnace lining is made of high-purity alumina lightweight fiber material, which has better insulation effect, energy conservation and consumption reduction.
7. The data storage function can store important sintering parameters for up to 30 days (8 hours per day).
8. Formula function, can pre store more than 100 formulas.
9. Multiple anti fooling functions make it safer for customers to use.
10. Networking function, using RJ45 interface and TCP/IP protocol, can connect the system to the upper computer (the upper computer needs to install correspondingsoftware).

Pressure measurement and monitoring

Using a mechanical pressure gauge, the outer shell of the gauge is an airtight structure, which can effectively protect the internal components from environmental impact and debris intrusion, and has strong corrosion and high temperature resistance.

Gas supply system

The gas flow rate is controlled by a float flowmeter, integrated with the equipment, and leak testing has been carried out before leaving the factory.

Equipment usage precautions

1. When the furnace temperature of the equipment is ≥ 300 ℃, it is prohibited to open the furnace to avoid injury;
2. When using the equipment, the pressure inside the furnace tube should not exceed 0.125MPa (absolute pressure) to prevent equipment damage caused by excessive pressure;
3. When used under vacuum, the operating temperature of the equipment shall not exceed 800 ℃.
4. The internal pressure of the gas supply steel cylinder is relatively high. When gas is introduced into the furnace tube, a pressure reducing valve must be installed on the cylinder. It is recommended to purchase a small pressure reducing valve for testing, with a range of 0.01MPa-0.15MPa, which will be more precise and safe to use.
5. When the temperature of the furnace body exceeds 1000 ℃, the furnace tube cannot be in a vacuum state, and the air pressure inside the furnace tube must be equivalent to atmospheric pressure and maintained at atmospheric pressure;
6. Long term use temperature of high-purity quartz tube ≤ 1100 ℃
7. It is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube during heating experiments. If it is necessary to close the gas valve to heat the sample, it is necessary to always pay attention to the reading on the pressure gauge. The absolute pressure gauge reading should not exceed 0.15MPa. The exhaust end valve must be immediately opened to prevent accidents (such as furnace tube rupture, flange flying out, etc.).
