1. Product introduction
1. Double beam photometric system, combined with advanced circuit measurement and control system, make the instrument have high stability and extremely low noise.
2. The newly designed excellent optical system and high-performance holographic blazed grating ensure the low stray light of the instrument, so that the instrument can work stably at all wavelengths with four decimal places of absorbance value (two decimal places of transmittance value).
3. Fully automatic control system and advanced design concept ensure high reliability and stability of the instrument.
4. The design of the sample chamber with detachable structure makes it easy to replace different accessories to meet different analysis needs.
5. The spacious open light source room design makes the replacement of the light source more convenient.
6. Imported components are selected for key parts to ensure high reliability of instrument performance.
7. The Chinese and English operating software developed under the windows environment provides a wealth of unique analysis functions.
