Working Principle
The multi-parameter water quality measuring instrument uses a single wavelength of light to pass through the sample to be tested, and according to Lambert-Beer's law, the concentration value of a substance contained in the sample is calculated by measuring the absorbance value.

3. The multi parameter water quality analyzer can take backup measures for the curve and data record calibrated by users, and can resume operation in case of accidental loss. 4. The instrument is equipped with various safety measures, both powering on and system set all need password. 5. The instrument has its own calibration function, which can effectively eliminate the drift error caused by long-term use. 6. The instrument adopts 5-inch large screen color touch screen operation, easy to operate. 7. The light intensity is divided into 16 levels and can be set arbitrarily, which can effectively solve the problem of measuring range expansion caused by signal strength. |
 8. Except the ex-factory curves, users can add, calibrate, and save curves in the instrument by themselves. 9. The curve can be inquired. Except the curve equation, the standard value of each standard substance, the corresponding absorbance, the calibration time and the number of the calibration personnel all can be inquired, so as to completely reproduce the state of calibration. 10. Type C can store 300 curves, 1000 records, and type D can store 3500 curves, 100000 records. 10. The optical system is optimized and upgraded (type D). The system is more stable, with better accuracy and stability. |
 11. When querying records, you can print a single or a whole page results. 12. The system has bilingual function and can switch between Chinese and English. |
 13.You can choose straight line method or broken line method for the instrument measurement. Choosing the broken line method can measure some parameters with poor linearity more accurately. 14. With one key recovery function, it can realize one key recovery when the factory curve and users' curve data records are lost due to accidents. |
