SIGNIFICANCE AND USE
Manganese is not present in natural waters but it is found
in various salts and minerals, frequently associated
with iron compounds. Manganese salts are used as
fertilizer additives, in ferroalloys (in 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).

its original packing materials.
CHEMICAL REACTION
The reaction between manganese and reagents causes a
violet tint in the sample which is proportional to the
manganese concentration.

INSTRUCTIONS
ISTR38042
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 [email protected].
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.);
• 1 checker disc (containing a mirror, a mirror holder
and the 38072 disc);
• 2 glass vials with caps;
• 1 plastic pipette (3 mL).
• Hold the checker disc so that
a light source illuminates the
samples from the top.
SPECIFICATIONS
READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• 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 20 mL of sample (up to the
mark).
• Keep the checker disc at a
distance of 30-40 cm (1216") 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 and
divide it by 3 to obtain mg/L (or ppm) of Manganese.
• Insert one of the vials into the left hand opening of the
checker disc. This is the blank.
• Add to the other vial 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.
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.

HEALTH AND SAFETY
• Remove the cap and insert the reacted sample into the
right hand opening of the checker disc.
The chemicals contained in this kit may be hazardous if
improperly handled. Read the relevant Health and Safety
Data Sheet before performing this test.
