Portable VA Analyzer

Portable voltammetric analyzers for the determination of trace levels of heavy metals in water in the field.

With the 946 Portable VA Analyzer, water can be analyzed for trace levels of heavy metals (e.g., arsenic, mercury, zinc, lead, copper, nickel, cobalt, or iron) on site instead of in the lab, giving you results within minutes.

  • Portable battery-powered analyzer for on-site analyses
  • Pre-defined methods available for straightforward operation
  • Semidisposable and disposable sensors for simple handling
  • Results within a few minutes
  • Suitable for analyses in accordance with WHO guideline values
  • Complete package with all accessories to get started immediately

Don't take the sample to the lab – Take the lab to the sample

The 946 Portable VA Analyzer allows you to take a sample, analyze it, and get the results in one go, eliminating the time-consuming task of taking samples to the laboratory.

The 946 Portable VA comes in a convenient transport case that contains all accessories you need to start measuring:

  • Instrument with compact, robust measuring cell and cables
  • scTRACE Gold sensor or holder for screen-printed electrodes
  • Reagent bottles, pipettes, and more accessories

Straightforward and quick heavy metal analysis
