| 1.This instrument adopts potassium permanganate oxidation-chemical measurement titration method, which can eliminate the error of color and turbidity; |
| 2. The unique design makes it have lower failure rate, maintenance, reagent consumption, higher cost performance and stronger anti-interference ability than similar products; |
| 3. adopts the inlet metering system, each sample is measured individually, accurate measurement, no reagent mixing cross contamination; |
| 4. The minimum titration volume of the titration system is 0.0025mL to ensure accurate measurement; |
| 5. Adopting imported FEP transparent hose, the diameter of the tube is larger than 1.0mm, which reduces the chances of clogging of water sample particles; |
| 6. Support zero verification and range verification, preventing system errors caused by zero drift and range drift; |
| 7. power failure protection design, with power failure, and then power up data automatic recovery function; |
| 8. Support multi-layer password protection function; |
| 9. Intelligent fault self-diagnosis function, instrument management and maintenance is very convenient; |
| 10. Support RS-232/RS485 output, with network function, through the network can realize data remote control; |
| 11. Adopt sequential injection analysis method, simple flow path, low reagent consumption and high automation; |
| 12. adopting multi-channel valve, strong anti-corrosion performance, long service life, safe and reliable. |
