What is manganese measured for?

Manganese (Mn) occurs naturally in groundwater and at high concentrations can lead to black deposits in pipes, discoloration and an unpleasant taste. The limit value for drinking water is 0.05 mg/l Mn (Drinking Water Ordinance).

In water treatment, manganese must be reliably monitored as it can pollute the filter systems. Photometric measurement enables precise determination over a wide concentration range.

How does the test set work?

The CALDUR® Manganese test set is based on the formaldoxime method. After adding three reagents to the water sample, an orange-red coloration develops within 10 minutes, the intensity of which is precisely determined with the WINLAB Data Line photometer.

Advantages of the CALDUR® test set

• Large measuring range 0.05 – 20 mg/l Mn

  From the drinking water limit to high industrial concentrations

• 100 provisions per set

  Economical for regular checks

• High precision due to photometric evaluation

  Objective, reproducible measurement results with the WINLAB Data Line

• Proven formaldoxime method

  Specific for manganese, little interference

What is manganese measured for?

Manganese (Mn) is a naturally occurring heavy metal that is frequently found in groundwater and surface waters. The limit value for drinking water is 0.05 mg/l Mn (Drinking Water Ordinance).

Elevated manganese concentrations lead to black-brown deposits in pipes, discoloration of the water and a metallic taste. In waterworks, manganese must be reliably removed, as even low concentrations can lead to operational disruptions.

Manganese can cause deposits and corrosion in cooling water systems and industrial treatment. Regular monitoring is therefore essential.

How does the test set work?

The CALDUR® Manganese Test Set – Colorimetric is based on the formaldoxime method. After adding three reagents to the water sample, a colored complex is formed within 10 minutes, the intensity of which is proportional to the manganese concentration.

The measured value is determined by direct color comparison with a supplied color chart.

Advantages of the CALDUR® test set

• Sensitive measuring range 0.03 – 1.0 mg/l Mn

  Already detects concentrations below the drinking water limit value

• 100 provisions per set

  Economical for regular checks

• Proven formaldoxime method

  Selective for manganese, low interference

• Easy handling with color card

  Fast on-site determination without measuring devices

• Robust plastic housing with hinged lid

  Safe transportation and protection of reagents
