HI 38072
Test Kit for
Irrigation Water
Manganese is not occurring in natural waters but it is
found in various salts and minerals, frequently associated
with iron compounds. Manganese salts are used as
fertilizer's additives, in ferroalloys (in the steel manufacture),
in non-ferrous alloys as it improves their corrosion resistance
and hardness.
Manganese is not considered to be toxic to man and
aquatic life and it is ingested as a trace nutrient, both in
food and water. Nonetheless manganese has been limited
in drinking water since it causes tenacious stains to laundry
and because it produces objectionable tastes in beverages.
Manganese is commonly found in domestic wastewater,
industrial effluents and receiving streams.
Note: mg/L is equivalent to ppm (parts per million).
Note: Any damaged or defective item must be returned in
its original packing materials.
The reaction between manganese and reagents causes a
violet tint in the sample which is proportional to the
manganese concentration.
Dear Customer,
Thank you for choosing a Hanna Instruments 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 damage,
notify your Dealer or the nearest Hanna office immediately.
Each kit is supplied with:
• HI 93709A-0 Manganese High Range Reagent A,
packets (100 pcs.);
• HI 93709B-0 Manganese High Range Reagent B,
packets (100 pcs.);
• Deionized Water, 2 bottles (2 x 230 mL);
• 1 checker disc (containing a mirror, a mirror holder
and the 38072 disc);
• 2 glass vials with caps;
• 1 plastic pipette (3 mL).
• 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 illuminates
the samples from the top.
• Verify that the mirror, its holder and the disc are
pre-installed in the checker disc. If not, install them as
shown in the figure.
• Using the plastic pipette, fill each
glass vial with 7.5 mL of sample (up
to the mark).
• Insert one of them into the left hand
opening of the checker disc. This is the
• Add to the other vial
Deionized Water up
to the 10 mL mark.
Replace the cap and
shake to mix.
• Remove the cap
and add 1 packet
of HI 93709A-0
reagent. Replace
the cap and swirl
to mix.
• Remove the cap
and add 1 packet
of HI 93709B-0
reagent. Replace
the cap and swirl
to mix.
• Wait for 1 minute
and 30 seconds to
allow reaction to
occur. This is the
reacted sample.
• Keep the checker disc at a distance of 30-40 cm (1216") from the eyes to match the color. 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 Manganese.
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.
Suspended 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: Calcium above 700 ppm, magnesium above
100000 ppm, chloride above 7000 ppm, iron above
5 ppm.
