Multifunctional Portable Heavy Metal Analyzer DW-HM-5000

DW-HM-5000 (multifunctional) portable heavy metal analyzer integrates the high sensitivity, authority- recognized “Anodic stripping method” and the fast, good anti-interference, national standard “Colorimetric method”.

Performance of Multifunctional Portable Heavy Metal Analyzer


  • Rapid detection

less than 5 minutes with the fastest detection of less than 30 seconds

  • Wide detection range

typical heavy metal ions for detection include Cu, Cd, Pb, Zn, Hg, As, Cr, Ni, Mn, and Tl, etc.; the measuring type of metal is expandable using a personal computer(PC)

  • High precision 

up to 1ppb with a detected Ion limit of less than 0.5ppb

  • Electrode uniques

reference electrode with a special wintering technique for stable performance, easy maintenance, and replacement

  • Smart

smart programs for easy operation

  • Diversity

the records of standard samples are optional to reuse; user-defined time priority or accuracy priority

  • Low cost

inexpensive consumables and low consumption

Safe use; nontoxic ancillary reagents ensure personal safety

Applications of Multifunctional Portable Heavy Metal Analyzer

  • Portable, applicable for on-site emergency detection, e.g. water environmental water environment monitoring;
  • Laboratory heavy metal detection and analysis  
  • Surface- water, groundwater. seawater. Industrial wastewater, drinking water, and other environmental water monitoring
  • Widely used in the detection of the heavy metal content in the soil solid waste and other solid substances (by extracting)

PC Communication

The instrument can be connected to a PC through a USB port, supported by the corresponding PC-side software to achieve the following functions;

  1. Configurate15 programmable analysis menus in the instrument to enable the users to easy configuration of the measurement parameters and methods
  2. Operate the instrument, such as hardware detection, electrode maintenance, measurement upload history, spectrum analysis, and algorithm application analysis, etc.

Software advantages

  • Bilingual interface, friendly smart design, easy operation;
  • The optimized patent algorithm integration can further improve the measurement accuracy to the sub-ppb level;
  • Users can take advantage of the PC software to develop more the heavy metal detection method and electrolyte reagents,to adapt for the detection of a wider variety of metals and various water bodies in varied circumstances;
  • The spectra with the integral io n of the patent algorithm can be directly displayed on an LCD to guarantee the same accuracy as that analyzed with a PC;

Detection case

Simultaneous detection of the concentration Cd, Pb, and Cu in the synthetic water sample

In this case, the synthesized mixed water sample contains Cd. Pb and Cu with a concentration of 100ppb respectively.

Firstly, scan the blank solution (no peak smoothing)

Secondly, scan the standard solution (Cd, Pb, and Cu with the concentration of 100ppb respectively to get the stripping peak current of Cd, Pb, and Cu

Thirdly, scan the synthetic water sample to get the stripping peak current of Cd, Pb, and Cu

Finally, calculate the concentration which is proportional to the peak current.
