Product Overview
 
G21 ammonia nitrogen rapid tester is a new water quality testing equipment with high cost performance introduced by Green Carry in 2019. It adopts sealed catalytic digestion, then uses colorimetry for measurement, advanced cold light source, narrow-band interference technology and microcomputer to automatically process data, and directly display and print the concentration value of samples.
 
The device is equipped with a 4.3-inch full-color LCD screen and a flat UI design interface, which can make the test data display more intuitively.
 
Guide the detection mode, reduce the learning cost, and the user can get started simply and quickly.
 
The equipment is equipped with prefabricated reagents, so users need not mix a variety of detection reagents, but only need to add detected water samples.
 
 
Detection principle
 
G21 type ammonia nitrogen rapid tester, Ammonia nitrogen in the form of free ammonia or ammonium ions reacts with Nessler's reagent to form a yellowish brown complex, The absorbance of the complex is directly proportional to the ammonia nitrogen content. The absorbance value of the complex is obtained by colorimetry, and the ammonia nitrogen detection items are selected. The imported cold light source emits the light source signal to the sensor, and the data is processed by RAM processor, and the sample concentration value is directly fed back and displayed in unit mg/L..
