Principle
Diphenylcarbazide colorimetry
Characteristics
1.Measuring method stipulated by national standard (GB7467-87) keeps good correlation with manual operation analysis;
2. Wide measurement range (0-5) mg/L allows range changeover according to the water samples;
3. Power-off protection is designed to prevent the apparatus from damage and data records from losing;
4.Intelligent design of fault self-diagnosis makes it convenient for apparatus management and maintenance;
5.Sampling mode can be set as timing sample;
6.Dosages of the two test reagents are less than 1ml, with low operating cost;
7.Strong anti-interference ability is applicable to the industrial site;
8.Can be widely used in the monitoring of surface water and pollution source.
