CALDUR\u00ae Sulfide Test Set – Colorimetric<\/h2>\n

What is sulfide measured for?<\/h3>\n

Sulphide (S\u00b2-) is produced by the anaerobic decomposition of organic substances containing sulphur and can cause an unpleasant smell of rotten eggs as hydrogen sulphide (H\u2082S). Even low concentrations are corrosive and can damage pipelines and structures. <\/p>\n

Sulphide is harmful to health in higher concentrations<\/strong> and can cause respiratory and eye irritation in people who work with contaminated water. Sulphide is undesirable in drinking water treatment and must be reliably detected. <\/p>\n

In industrial water treatment, in sewage treatment plants and in groundwater samples, sulphide control is essential to prevent corrosion and ensure water quality.<\/p>\n

How does the test set work?<\/h3>\n

The CALDUR\u00ae Sulfide Test Set – Colorimetric is based on the DPD method. After adding two reagents to the water sample, a characteristic coloration develops within 7 minutes, the intensity of which is proportional to the sulfide concentration. <\/p>\n

Advantages of the CALDUR\u00ae test set<\/h3>\n
    \n
  • Sensitive measuring range 0.05 – 1.0 mg\/l S\u00b2-\n

    Detection of even low sulphide concentrations<\/p>\n<\/li>\n

  • 100 provisions per set\n

    Economical for regular checks<\/p>\n<\/li>\n

  • Easy handling\n

    Fast on-site determination without measuring devices<\/p>\n<\/li>\n

  • Proven DPD method\n

    Reliable and reproducible results<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
