It is designed and manufactured according to “Water quality-Determination of the chemical oxygen demand-Fast digestion-Spectrophotometric method”. It can test COD value in water in 20 minutes.
1. Quick and accurate test of chemical oxygen demand (COD) in surface water, reclaimed water, municipal wastewater and industrial wastewater.
2. The independent dual optical system has the advantages of direct reading, high accuracy, long service life and more stable.
3. The 3.5 inch color LCD screen, humanized operation hint, simple to use.
4. Self-calibration function of the instrument can be calculated and stored according to the standard sample, without manual production of curves.
5. Large and small font display mode is free to switch, showing clearer data and more detailed parameters.
6. It can transmit the current data and all stored historical data to the computer, and support USB transmission and infrared wireless transmission. (selecting)
7. Support both colorimetric cuvette and colorimetric tubes.
8. The printer can print current data and all stored historical data.
9. Equipped with professional consumables reagents, the working procedures are greatly reduced, the measurement is simpler and the results are more accurate.
10. The instrument adopts the self-designed non-metal case. The machine is beautiful and generous.
11. Support twelve thousand historical data storage (date, time, parameters, measurement results).
