Product details
Product Introduction
This product utilizes sealed catalytic digestion followed by colorimetric measurement. The instrument adopts advanced cold light source, narrowband interference technology, and microcomputer automatic data processing to directly display the COD (mg/L) value of the sample. This instrument is widely used in environmental monitoring, sewage treatment, colleges, research institutions and other departments

Instrument characteristics
|
2. The measuring instrument is a cold light source and narrowband interferometric optical system with good optical stability. 3. Comparing colors in a colorimetric dish results in better linearity. 4. LCD large screen with Chinese display, easy and intuitive operation. 5. The digestion instrument has PID automatic temperature control and timing, with high accuracy. 6. Simple and time-saving operation, no need to change the tube for digestion colorimetry. 7. The digestion temperature and time can be infinitely set for other purposes. 8. It can save 10 standard curves and 500 measured values without losing them when powered off. |
Separating the measuring instrument from the digestion instrument does not affect the stability of the optical system.Configuration List
