  • Countdown-timer to streamline your analysis

Detect very low concentrations of impurities in water

The application

  • Drinking water, groundwater, freshwater, mineral water and process water should be regularly tested for a variety of parameters.
  • Analysis often requires high measurement sensitivities down to the ppb range.

Our solution: MColortestTM with color-card comparator

The MColortestTM system is designed for highly sensitive, fast analysis
of any water sample. It includes a color-card comparator, which allows you to compare the reaction color of the sample with a high-quality color scale for accurate evaluation.

Benefits

  • Unique brilliance and fine color graduation for precise analysis • Easy-to-use visual tests with fast results
  • Very low (ppb range) to medium concentrations can be tested • Excellent measurement sensitivity

Highly reliable and portable, MQuantTM test strips are designed for semi-quantitative determination of ions and compounds. These versatile strips can be used in concentration ranges as low as below 1 mg/L up to the g/L range.

The test strips save you considerable time and costs during analyses, quality checks and in-process controls. Thanks to the PET film backing material and the low reagent content, the test strips are also easy
to dispose of.

MColorpHastTM makes pH measurement easier than ever. No instruments, sample preparation, maintenance, or cleaning electrodes. Simply read the color. The rapid method offers an accurate color scale for clear, reliable results.

It’s suitable for all types of media in environmental analysisand industrial in-process controls – even for highly turbid liquids.With our broad range of pH tests, you'll always have the optimal solution for your application.
