Iron

Remove the 3 vials and pH strip/scale from the large test tube
Add 10ml of the sample solution to be tested to the large test tube
Check pH of the sample solution by dipping the pH strip (about 1/2 cm.) into the solution and comparing to the pH scale provided. If the pH is higher than 4.0 add 1 drop of reagent 2 and then check with the pH strip again after cutting off the used section.
If the pH is below 3.0, add one drop of reagent 3 and then check with the pH strip again after cutting off the used section.
Repeat procedures (iii) and (iv) if necessary until the pH reading is between 3.0 to 4.0
The solution is now ready for testing

Conducting the test

Add all the contents in the vial with yellow cap (reagent 1) to the sample solution in the test tube
Cap the test tube and gently turn it up and down 2 - 3 times
Wait 3 minutes and check the colour of the solutions against the colour strip provided on the box
Take note of the reading from the colour chart
If the result is higher than 0.25 ppm (maximum range), and a more detailed result is required, dilute the original sample solution with distilled water by 5 or 10 times the volume and re-test with another kit. Then multiply the result by 5 or 10 to obtain correct value in ppm.

The numbers indicate parts per million.
