The world's first fully automated real-time online lead（Pb）Arsenic（As）Wait, waitppbGrade water quality warning heavy metal analyzer, measuring arsenic, mercury, lead, copper, zinc, cadmium, nickel, cobalt.

Brief introduction

Anodic stripping voltammetry（ASV）With extremely low cost and high sensitivity, it is widely used in environmental online monitoring, tap water monitoring, electroplating and surface treatment industry wastewater monitoring, food, pharmaceutical, pharmaceutical wastewater monitoring and other fields. AmericaEPAThe institution has listed it as a standard testing method, such asEPA7063and7072Wait.

2、 Product principle

anodic stripping voltammetry(ASV)It is an electrochemical analysis method for measuring multiple metals in various interstitium, anodic stripping voltammetry(ASV)It is pre placed at a constant potential(Equivalent to the potential at which the maximum current is generated on the cathode of the ion)Concentrate the analyte on the electrode and then shift the potential of the microelectrode from negative to positive, causing the enriched substance to dissolve in the opposite direction(ASV)And the method of measuring by volt ampere curve. This method has been widely used in the detection of heavy metal ions.

3、 Product Features

1、 Adjustable touch screen, reporting real-time metal content levels

2、 Simple and convenient human-machine interface（HMI）

3、 Data logging, which can be used to create reports or backup data

（3） Low operating costs

1、 Continuously replaceable reagent disks, each disk can provide up to1000Secondary sample analysis

2、 On site module replacement, easy maintenance, only needed per month5Replace reagents in minutes

3、 System automatic diagnosis and sample calibration

4、 Technical parameters

5、 Application Fields

1、 Arsenic removal process from tap water

AmericaEPAThe regulation specifies the treatment technology for arsenic in tap water processes, in order to ensure the provision of safe drinking water,The arsenic content cannot exceed10ppb

2、 Municipal sewage treatment process

Adjust and save the amount of chemical reagents (such as coagulants) according to the production process and technological flow, to prevent production losses and chaos caused by sudden accidents

3、 Industrial wastewater discharge monitoring

Ensure that the metal content in the discharged wastewater is lower than the regulations set by the Environmental Protection Bureau to avoid fines

4、 Industrial process water

It can monitor sudden failures in process integrity control to prevent significant losses in production.

6、 Performance specifications
