Technical Features

● Capable of testing 5 national standard samples simultaneously, offering significant testing efficiency advantages and reaching internationally leading levels. Increasing the number of ash cones significantly reduces testing time per ash cone, lowers energy consumption per ash cone, and reduces gas consumption per ash cone, aligning with national energy conservation and emission reduction policies.

● Advanced spectral illumination analysis technology ensures reliable identification of ash cone characteristics from room temperature to maximum temperature.

● Fully sealed furnace structure with only one gas inlet and outlet, ensuring stable furnace atmosphere.

● Automatic airtightness detection device enables quantitative testing of furnace airtightness.

● High-efficiency exhaust fan with real-time monitoring of fan operation ensures safe and stable instrument performance.

● External high-sensitivity gas alarm detection device automatically cuts off gas supply quickly upon detecting leakage.

● Fully automatic sample feeding mechanism with simple operation, smooth sample loading and unloading, minimizing risk of ash cone sample tipping.

● Optional oxidizing or weakly reducing test atmosphere conditions, achievable through gas flow method or sealed carbon method.

● Positive pressure dust removal technology extends maintenance intervals for observation port insulating glass.

● Testing software supports operator login permission management, complete recording of experimental process information, and networked transmission of test data.

1. This instrument is suitable for new materials like monocrystalline silicon and polycrystalline silicon, solving the historical inability to perform ash fusibility tests in the polycrystalline silicon industry.

2. While ordinary ash fusion point testers have a maximum furnace temperature of 1600°C, this instrument reaches 1800°C, enabling a wider range of sample testing and pioneering high-temperature ash fusion point testers.

3. Capable of holding 16 samples at once with an automatic sample feeding mechanism, offering convenient operation and greatly improved efficiency.
