YSHM-200W Outdoor portable Water quality heavy metal detector water quality analyzer hospital sewage measuring instrument
Portable water quality heavy metal analyzer is the latest second generation of upgraded products. The combination of high sensitivity authority recognized method "stripping voltammetry" and fast, good anti-interference national standard method "photometric colorimetry". Among them, stripping voltammetry has been listed as a standard test method by the United States EPA and other authoritative agencies, such as EPA7063 and 7472; Photometric colorimetry has been listed as a standard method in many countries and is widely used. It can be used in environmental emergency detection, tap water detection, industrial waste water detection and other fields.

Test instance
Simultaneous detection of heavy metal elements in water samples containing Cd, Pb and Zn
In this case, a mixed water sample containing several heavy metals was synthesized, respectively containing Cd, Yang and Zn, all of which were 100ppb. The contents of pot, lead and zinc in the quality control water sample were calculated by single calibration method
STEP1, scan the blank solution (smoothing without peaks is OK)
STEP2 Sweep the standard solution (inner Cd, 100ppb) to obtain the peak dissolution current values of cadmium and lead in the standard solution
STEP3. By scanning the quality control water sample (containing 76ppb of Cd, Pb and Zn), the dissolution peak current values of Pb and Zn in the water sample were obtained
STEP4. Through the proportional relationship between the peak current and the concentration, the content of pot, lead and zinc in the water sample was calculated
