The Salifert Phosphate test kit detects, in less than 5 seconds, the level of phosphate present.
There are two different ranges within the kit:
a low range for phosphate-phosphor from 0.01 - 1 mg/L
a medium range for phosphate-phosphor from 0.02 - 2 mg/L.
Sufficient for 60 tests.
Can be used for marine, fresh and garden pond water
Erroneous results might be obtained when the carbonate hardness is higher that 20dKH. This corresponds to an alkalinity of 7meq/l. Normally the carbonate hardness is well below the above mentioned values.
Irritating: PO4-1 contains < 3.5 M HCL.
R36/37/38: Irritating to eyes, respiratory system and skin.
S26: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.
Add with the syringe 10ml of water in the test vial
Add to this 4 drops of PO4-1 reagent and swirl the test vial gently for 10 seconds
Add to this 1 level scoop of PO4-2 reagent and swirl the contents gently for 30 seconds
Place the open test vial on top of the color shart on a part of the chart which is white and compare the colors looking from the top. Read the corresponding phosphate content. An intermediate color corresponds to an intermediate phosphate content.
The phosphate values are in ppm Phosphate. If you prefer a reading in ppm Phosphate-Phosphor then divide the reading by 3 or use the table given below.
Should you require an even higher sensitivity then double the water sample and the reagents. The scale should then be divided by 2.
