Full Description Specification Manuals

Using Hanna special reagents, our test kits measure the strength or weakness of a chemical presence according to the degree of colour saturation. Ie – if it is pale in colour, then the chemical concentration is low. If the colour is strong, then the chemical concentration is high. Simply add the reagent to the compound to be tested and match the colour gained against a colour chart included in the kit.

Iron MR, Checker disc; phenanthroline colorimetric chemical method.

Order Information:
Reagent kit for 100 tests (Fe).

The HI-38040 is a colorimetric chemical test kit that determines the total iron concentration with a 0.0 to 5.0 mg/L (ppm) range.

The HI-38040 is supplied with all of the necessary reagents and equipment to perform the analysis. The test kit contains enough reagents to perform approximately 100 tests.

  • All required materials are included with the test kit, such as the glass vials, plastic pipette, reagent packets, and Checker® disc
  • Readings from 0.0 to 5.0 mg/L are determined to 0.1mg/L resolution
  • Replacement reagents available – HI-38040-100

Significance of Use

Iron is naturally present in water in low concentrations, but it reaches high concentrations in wastewater effluents.

The iron concentration in water needs to be monitored because it becomes harmful above certain levels.

In domestic water for instance, iron can stain laundry, damage kitchenware, favour the growth of certain bacteria, and unpleasantly alter the taste of water. Iron is also an indicator of ongoing corrosion in water cooling and heating systems. Moreover, iron is normally monitored in mining wastewater to avoid contamination.
