Dear Customer,
Thank you for choosing a Hanna Product.
Please read the instruction sheet carefully before using the
test kit. It will provide you with the necessary information
for correct use of the kit. If you need additional information,
do not hesitate to e-mail us at tech@hannainst.com.
Remove the chemical test kit from the packing material and
examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable dam-
age, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:
• HI 3834-0 Reagent, packets (100 pcs);
• 1 checker disc (containing the 38040 disc);
• 2 glass vials with caps;
• 1 plastic pipette (3 mL).
Note: Any damaged or defective item must be returned in
its original packing materials.

SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE SIGNIFICANCE AND USE
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 (Fe ) state. The test is
2+
fast and easy. The checker disc makes it simple to obtain
the iron level in water.
Note: mg/L is equivalent to ppm (parts per million).

CHEMICAL REACTION CHEMICAL REACTION
Iron can exist as ferrous (Fe 2+ ) or ferric (Fe 3+ ) 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
• Using the plastic pipette, fill each glass
vial with 10 mL of sample (up to the
mark).
• Insert one of the vials into the left
10 mL
hand opening of the checker disc. This
is the blank.
• Add to the other
vial 1 packet of
HI 3834-0 re-
agent. Replace the
cap and shake to
mix.
• Wait for 3 minutes to allow reac-
tion to occur. This is the reacted
sample.
• Remove the cap and insert the reacted sample into the
right hand opening of the checker disc.
• Hold the checker disc so
that a light source illu-
minates the samples
from the back of the
windows.
• Keep the checker disc at a distance of 30-40 cm (12-
16") from the eyes to match the color, while having a
uniform background (e.g. a white sheet). Rotate the
disc while looking at the color test windows and stop
when you find the color match. Read the value in the
result window directly in mg/L (or ppm) of Iron.
For best results: Perform the reading three times and
take the average value (divide by 3 the sum of the
three numbers). Intensely colored samples will make
the color matching difficult and they should be
adequately treated before performing the test. Sus-
pended matter in large amounts should be removed
by prior filtration.
Caution: Ultraviolet radiation may cause fading of colors.
When not in use, keep the disc protected from light,
in a cool and dry place.
Interferences: Molybdate and Molybdenum above 50 ppm,
calcium above 10000 ppm (as CaCO ), magnesium
3
above 100000 ppm, chloride above 185000 ppm.
