•1 plastic vessel (20 mL).
Note: Any damaged or defective item must be returned in
its original packing materials.
HI 3834
Iron Test Kit
ISTR3834NR2 07/02 PRINTED IN ITALY
Generally, ground and surface water contains no more than
1 mg/L (ppm) iron; but due to mining and industrial
drainage, higher levels of iron have been observed. Iron in
water appears to be more of a nuisance than a hazard.
The presence of iron can stain laundry and give water a
bittersweet taste.
The Hanna Test Kit determines the iron concentration in
water by conversion of the ferrous (Fe2+) state. The test is
fast, easy and safe. The color cube makes it simple to obtain
the iron level in water.
Range 0 to 5 mg/L (ppm) Iron
Smallest Increment 1 mg/L (ppm) Iron
Analysis Method Colorimetric
Sample Size 10 mL
Number of Tests 50 (average)
Case Dimensions 220x145x55 mm (8.7x5.7x2.1")
Shipping Weight 142,5 g (5 oz.)

Iron can exist as ferrous (Fe2+) or ferric (Fe3+) ions. The
Hanna Test Kit determines total iron levels in water via a
colorimetric method. First all ferric ions are reduced by
sodium sulfite to ferrous ions. Phenanthroline complexes with
ferrous ion to form an orange colored solution. The color
intensity of the solution determines the iron concentration.
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Remove the cap from the plastic vessel. Rinse the plastic
vessel with water sample, fill it to 10 mL mark.
• Add 1 packet of reagent HI 3834-0.
• Replace the cap and mix solution until solids dissolve.
• Remove the cap and transfer the solution into the color
comparator cube. Let set for 4 minutes.
• Determine which color matches the solution in the cube
and record the result as mg/L (ppm) iron.
