Product main features:

1. Instrument performance: advanced electronics system, 24-bit voltage digital sampling.

2. Stable and reliable quality: The beam dynamic feedback proportional recording photometry system ensures baseline stability. Key components such as photomultiplier tubes and receiving systems are all imported, ensuring the stability, reliability and long life of the instrument.

3. Accurate measurement: Imported high-quality full-band products are used to further reduce the stray light of the instrument and make the instrument analysis more accurate.

4. Function expansion: liquid pool, gas chamber, integrating sphere (upgrade required).

5. An integrating sphere device can be added to facilitate testing and analysis of diffuse reflection materials.

6.The device reserves a wireless upload interface for data upgrade from the main station.
