SALIENT FEATURES
- It can measure a variety of conventional water parameters, such as COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, chromaticity, heavy metal ions in suspended solids, etc. The concentration can be read directly and the measurement results are more accurate.
- The unique high-precision filter system makes the instrument more stable and the measurement more precise.
- Using cold light source, narrow-band interference technology, the lifespan of the light source is up to 100,000 hours.
- Support users to build their own curves according to different measurement requirements, and the segmentation coefficient K can be adjusted according to measurement requirements.
- With the new ARM9 chip, the instrument is more responsive and capable of up to 500 M memory.
- With Lab-yy prefabricated reagents, the experimental steps are greatly reduced, measurement is easier and data is more accurate.
