The
fluoride test is especially suited for rapid control of
fluoride concentrations. Its purpose is to define
concentration ranges and detect values which fall short
of or exceed given limits.
Color
Reaction:
The pink test disc is bleached by fluoride
containing hydrochloric acid solutions. The size of the
bleached area corresponds to the total fluoride
concentration.

Test Kit Contents:
3 test discs
1 bottle
fluoride reagent test
solution (hydrochloric acid)
1 disc color scale,
1 pin/needle,
Fluoride
Test Instructions:
1. Fill a 20ml (beaker/small
plastic container) about
half-way with the water sample (about 10ml)
2. Add
20 drops hydrochloric acid (Fluoride Reagent). The pH value must be below
1.
3. Remove one fluoride test disc from ziplock
bag. Close bag immediately.
4. Pierce the round test
disc in the middle with the enclosed needle!
5.
Throw test disc into the water sample and submerge
completely.
6. after 5 - 7 minutes the test disc is
saturated with the solution, i.e. it does not absorb any
more liquid. At the latest 2 minutes after saturation
remove the test disc from the sample and compare the
size of the bleached zone with the disc color scale.
This test will give you a reaction when the sample water
has at least 2 parts per million of fluoride. Otherwise
no changes will be observed.
For high
concentrations the sample has to be diluted. After
evaluation the dilution has to be taken into account.
Storage
Avoid
exposing the sticks to sunlight and moisture. Store the
kit below + 30 degrees centigrade in a dry place.
We
included three tests discs so you can test your tap water,
then the water produced by your water filter to see if
fluoride was removed by filtration and one extra disc if
something went wrong with your testing.
