Precautions for Use

1. When using the equipment, the internal pressure of the furnace tube must not exceed 0.125MPa (absolute pressure) to prevent equipment damage.
2. Gas cylinders have high internal pressure. When feeding gas into the furnace tube, a pressure-reducing valve must be installed on the gas cylinder. It is recommended to select a small pressure-reducing valve with a range of 0.01MPa-0.15MPa for more accurate and safer operation.
3. When the furnace temperature exceeds 1000°C, the furnace tube should not be under vacuum. The internal pressure of the furnace tube should be at atmospheric pressure.
4. During heating experiments, it is not recommended to close the gas inlet and outlet valves at the furnace tube flanged ends. If gas valves must be closed during sample heating, constantly monitor the pressure gauge reading. The absolute pressure gauge reading should not exceed 0.15MPa.
