Introduction:

Ammonia nitrogen refers to nitrogen present in the form of free ammonia and ammonium ions in water.

KN-NH20 is a laboratory intelligent ammonia nitrogen analyzer, which is a multifunctional laboratory instrument for the determination of ammonia nitrogen. It has high test accuracy, wide test range and powerful functions, and is suitable for research institutes and government monitoring agencies.

Features:

1. Rapid and accurate determination of ammonia nitrogen concentration in surface water, intermediate water, municipal sewage and industrial wastewater

2. Independent single optical path non-interference system, high precision, long life and more stable

3. High-definition LCD color LCD display, user-friendly operation prompt, simpler operation

4. Built-in 99 curves, one of which is the ammonia nitrogen standard curve

5. Chinese display interface, full Chinese keyboard, easy for operators to operate

6. Unique external printer, convenient and compact

7. Support 1000 pieces of stored data, convenient for users to view historical data

8. Single sample measurement time is 15 minutes, accurate and fast

9. Built-in 99 curves, including one ammonia nitrogen standard curve, no need to adjust, can be used directly, 98 extended curves can be freely applied under different conditions, different environments, different wastewater conditions, etc.

10. Support curve automatic correction and save automatically

11. Support historical data storage (date, time, parameters, measurement results)

12. Large screen Chinese display keyboard, concentration direct reading

13. Cold light source, narrow-band interference, light source life of 100,000 hours
