• For approx. 80 measurements. For fresh- and saltwater.
• Measurement range from 0.05 to 1-5 mg/l iron.
• Responds to all dissolved iron compounds.
• Colour scale with 9 colours from colourless to dark violet. Laboratory compensation system compensates water discoloration. Includes syringe to measure amount of water.

The JBL Iron Test-Set Fe is designed for the measurement and routine control of the iron content in saltwater and freshwater within the range 0.05-1.5 mg/litre (ppm). The compensation method developed specially by JBL allows precise and reliable results to be obtained even in moderately discoloured aquarium water, e.g. caused by peat filters and disease treatment.
(Recommended level: 0.05 - 0.2 mg/l iron in freshwater)

INSTRUCTION:

1. Repeatedly rinse both test jars with the aquarium water to be tested.
2. Use the enclosed syringe to fill each of the test jars with 5 ml of sample water.
3. Add 5 drops of Fe-reagent to one of the test jars and mix by agitating. Allow to settle for exactly 5 minutes.
4. Place both test jars into the comparator block: the jar with added reagent into the smooth end of the comparator block, the jar with the untreated test water (blank sample) into the notched end of the comparator block.
5. Move the comparator block together with the jars side to side over the colour chart until the colour of the sample with added reagent matches the colour of the blank sample.
6. Read the iron content in the notch of the comparator.
