0.00 - 1.00 ppm Phosphate (PO43-) Range:
1- Verify that the mirror, its holder and the 38061 disc
are pre-installed in the checker disc. If not, install them
as shown in the figure.

2- Using the pipette, add to each glass
vial 10 mL of sample (up to the
mark).
Significance and use
3- Insert one of them into the left hand opening of the
checker disc. This is the blank.
Phosphorus occurs in natural waters and in wastewaters almost
entirely as phosphates (PO43-). Large quantity of phosphate arise
from laundering industries as it is used in many cleaning
preparations, from soil run-off and sewage.
Phosphorus is essential to plants since it contributes to the
formation of buds, roots and blooming as well as lignification
and its lack results in stifled plants or pale green color with
reddish pigmentation on leaves' edges.
On the other hand, an extensive discharge of phosphorus in
water is the major cause of eutrophication, which is an abnormal
and excessive growth of aquatic plants.
Note: mg/L is equivalent to ppm (parts per million).
4- Add to the other glass vial 1 packet of HI 93713-0
Reagent. Replace the cap and shake gently for 2 minutes.
This is the reacted sample.
8- 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 Phosphate. To
convert this result to mg/L (ppm) of Phosphorus, divide
it by 3.1.
0.0 - 5.0 ppm Phosphate (PO43-) Range:
1- Remove the mirror, if installed, and insert only the
38073 disc as shown in the figure.

Note: Any damaged or defective item must be returned in
its original packing materials.
7- Hold the checker disc so that a light source illuminates
the samples from the top.

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 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 93713-0 Reagent, packets (100 pcs);
• Deionized Water, 1 bottle (500 mL);
• 1 checker disc (including a mirror, a mirror holder ,
the 38061 and the 38073 discs);
• 2 glass vials with caps;
• 1 plastic pipette (3 mL);
• 1 long plastic pipette;
• 1 syringe (1 mL) with tip.
6- Remove the cap and insert the reacted sample into the
right hand opening of the checker disc.
Adaptation of the ascorbic acid method. The reaction between
phosphate and the reagent causes a blue tint in the sample.
5- Wait for 3 minutes to allow reaction
to occur.
2- Using the pipette, add to each
glass vial 7.5 mL of sample (up
to the mark).
3- Insert one of them into the left hand opening of the
checker disc. This is the blank.
4- Add to the other glass vial 1 packet of HI 93713-0
Reagent. Replace the cap and shake gently for 2 minutes.
This is the reacted sample.
0 - 50 ppm Phosphate (PO43-) Range:
1- Remove the mirror, if installed, and insert only the
38073 disc as shown in the figure.
5- Remove the cap and add to the other glass vial
1 packet of HI 93713-0 Reagent. Replace the cap and
shake gently for 2 minutes. This is the reacted sample.
4- Wait for 3 minutes to allow reaction to
occur.
5- Remove the cap and insert the reacted sample into the
right hand opening of the checker disc.
6- Hold the checker disc so that a light source illuminates
the samples from the back of the windows.
2- Using the 3 mL pipette, add to one of
the glass vials 5 mL of sample (up to the
mark) and insert the vial into the left
hand opening of the checker disc. This is
the blank.
3- Using the syringe, add to the other vial 0.75 mL of
sample.
Note: to measure exactly 0.75 mL of sample with the
syringe, push the plunger completely into the syringe
and insert the tip into sample. Pull the plunger out
until the lower edge of the seal is on 0.0 mL mark of
the syringe. Insert the syringe into the vial and push
the sample out until the lower edge of the seal is on
the 0.75 mL mark (the longer mark between 0.7
and 0.8).
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
determination 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:
iron above 5 ppm; copper above 10 ppm; hydrogen
sulfide, arsenate and highly buffered samples.
Accessories
6- Wait for 3 minutes to allow reaction
to occur.
7- Remove the cap and insert the reacted sample into the
right hand opening of the checker disc.
8- Hold the checker disc so that a light source illuminates
the samples from the back of the windows.

while looking at the color test windows and stop when
you find the color match.
8- Read the value in the result window, divide it by 10 and
record it in mg/L (or ppm) of Phosphate. To convert this
result to mg/L (ppm) of Phosphorus, divide it by 3.1.

Use the long plastic pipette to add deionized water up
to the 7.5 mL mark, replace the cap and swirl to mix.
10- Read the value in the result window directly in mg/L
(or ppm) of Phosphate. To convert this value to mg/L
