Multi parameter water quality COD ammonia nitrogen analyzer

SH-200Multi parameter water quality COD ammonia nitrogen analyzerMain functional features

1. doubleLCDDisplay, large screen LCD backlit display,240*128Dot matrix, Chinese operating interface, user-friendly programming.

2. The measurement range is wide and can be switched according to the actual situation of the water sample.

3. The determination and digestion systems are designed separately, with independent power control, and the operation process can be carried out separately without affecting each other;

4. Automatic temperature control system,PIDRegulating technology ensures constant temperature and high precision during the digestion process;

5. 1point to7Point correction mode, automatically calculates slope, intercept, and correlation coefficient, with high measurement accuracy.

6. Intelligent design for fault self diagnosis makes instrument management and maintenance simple and convenient.

7. The instrument has a built-in real-time clock, and each measurement record has a measurement timestamp for easy statistics and queries;

8. Large capacity data storage, power-off protection design, ensuring that the instrument is not damaged and data recording is not compromisedlose.

9. Strong anti-interference ability, suitable for industrial sites, and can be widely used for monitoring surface water and pollution sources.

10. The instrument adopts a semiconductor cold light source emitter with an optical circuit design that has strong anti-interference ability, high measurement data accuracy, and good stability. The lifespan of the light source can reach tens of thousands of hours.

11. Equipped with a data output interface, it can be connected to a computer to transmit measurement data to the computer;

12. The instrument comes with a thermal printer that can directly print measurement data and historical data;

13. Low reagent usage, low operating costs, and strong anti-interference ability.
