DS-NH200A Ammonia Nitrogen Analyzer

1、 Instrument description:
DS-NH200A Ammonia Nitrogen AnalyzerBy combining the Nessler's reagent colorimetric method specified in GB7479-87 with computer technology, the microcomputer photoelectron colorimetric detection principle is applied to replace the traditional visual colorimetric method, eliminating human errors and greatly improving measurement resolution. The automation of the measurement process has been achieved. It can be widely applied to the monitoring of sewage outlets of factories and mining enterprises, the monitoring of imports and exports of urban sewage treatment plants, the monitoring of water quality of Rivers and Lakes, and the process control of sewage treatment facilities.

IIDS-NH200A Ammonia Nitrogen AnalyzerFeatures：
The measurement method * complies with the provisions of the national standard GB 7479-87 and has a good correlation with manual analysis.
● Large screen LCD backlit display, pure Chinese operation interface, user-friendly program design.
The measurement range is wide and can be automatically switched according to the actual situation of the water sample.
Equipped with a large capacity lithium battery, it can be used for both AC and DC purposes and can be used for portable outdoor applications.
● Large capacity data storage, power outage protection design ensures that the instrument is not damaged and data records are not lost.
The calibration mode from 1 o'clock to 7 o'clock automatically calculates slope, intercept, and correlation coefficient, with high measurement accuracy.
Intelligent design for fault self diagnosis makes instrument management and maintenance simple and convenient.
Strong anti-interference ability, suitable for industrial sites.
It can be widely used for monitoring surface water and pollution sources.
Using * semiconductor cold light source emitter, the lifespan of the light source can reach tens of thousands of hours.
Can connect to a computer to export measurement data, and can connect to a printer to automatically print measurement data.
Low reagent usage, low operating costs, and strong anti-interference ability.
