With the 946 Portable VA Analyzer from Metrohm, there is now such an alternative. A dedicated solution for water analysis, the 946 Portable VA Analyzer enables fast and straightforward in-field determination of heavy metals typically determined in water with the sensitivity, accu-racy, and re producibility required to monitor the WHO guideline values. The 946 Portable VA Analyzer is ... • ready to measure in minutes, anywhere – portable carrying case complete with instrument, measuring stand, accessories, and bottles. • battery powered – no access to power grid required! • straightforward to use – simply start predefined methods and get the results shown a few minutes later.
