Features:
1. It has high resolution and can precisely measure the absorption of light at different wavelengths.
2. It supports multiple measurement modes, allowing users to select the appropriate mode based on different experimental requirements, which enhances the instrument's versatility and flexibility.
3. The instrument has an automatic calibration function that can automatically detect and correct the instrument's performance, ensuring the accuracy of measurement results.
4. The built-in diagnostic program can quickly detect instrument faults, facilitating maintenance and repair.
5. The automatic light gate ensures the service life of the photoelectric sensor, making instrument testing simpler.
6. The UV-Vis spectrophotometer can complete full wavelength range scanning in a short time, significantly improving work efficiency.

Precautions:
1. The instrument should be placed in a stable, dust-free, and vibration-free environment, avoiding direct exposure to strong light and interference from strong magnetic fields.
2. Do not place it in any area with gases containing organic or inorganic reagents that may cause absorption in the ultraviolet region.
3. Do not open the window or door of the measurement chamber during the measurement process, as this will affect the accuracy of the measurement results.
4. Regularly clean the surface of the instrument with a clean soft cloth. Do not use cleaning agents containing chemical components. The cuvette slot can only be cleaned with lint-free cotton swabs dipped in ethanol or isopropyl alcohol.
5. Regularly calibrate the instrument's wavelength and absorbance readings using standard filters or standard solutions. Regularly inspect and replace vulnerable parts such as the light source and detector.
