visocolor ECO Iron One Test Kit

Method

Colorimetric determination of Fe(II) and Fe(III) ions with a triazine derivate

Measurement range:

0.04–1.0 mg/L Fe

*Contents of test kit (refill pack):**
sufficient for 200 tests

• 30 mL Fe-1*
• 2 screw-plug measuring glasses
• 1 slide comparator
• 1 color chart
• 1 plastic syringe 5 mL
• 1 instruction for use*

Hazard warning:
Information regarding safety can be found on the box’ label and in the safety data sheet. You can download the SDS from www.mn-net.com/SDS.

Instructions for use:
Also refer to the pictogram on the back of the color chart

•  Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe.
• Place a measuring glass on position A in the comparator.
• Only add the reagent to measuring glass B.
•  Add 5 drops of Fe-1, seal the glass and mix.
•  Open the glass after 3 min and place it on position B in the comparator.
•  Slide the comparator until the colors match in the inspection hole on top.
• Check the measurement reading in the recess on the comparator reed.
• Mid-values can be estimated.
•  After use, rinse out both measuring glasses thoroughly and seal them.
• The reagents can also be used for the photometric evaluation with photometers PF-12 and PF-12Plus.
• This technique can be used also for analyzing sea water.

Disposing of the samples:
Information regarding disposal can be found in the safety data sheet. You can download the SDS from www.mn-net.com/SDS
