- Cold light and monochromatic light as light source, optics stability is much better, and cannot be interfered by all kinds of light.
- Use PID automatically control heating temperature, higher temperature accuracy.
- Operating is very convenient.
- Separate high temperature heating device from colorimetric part:, eliminate the influence of the high temperature.
- High efficiency, can measure 20 COD water samples per time, and measuring 1 batch samples only cost about 20 minutes.
- Can store 8 work curves(may set by user), and store 255 COD records and 100 ammonia nitrogen records with time label.
- The datas stored are nonvolatile
