LaMotte CORROSION CONTROL Test Kit - Manual (Page 11)

PHOS PHATE IN WA TER
IN TRO DUC TION
If part of your overall corrosion control program includes the addition of a
phosphate compound to inhibit corrosion in your potable water supply, a
phosphate test should be performed to measure Orthophosphate. Follow
instructions below.

)
1. Fill the test tube (0843) to the mark with the water sample.
2. Use the 1.0 mL pipet (0354) to add 1.0 mL of *Phosphate Acid
Reagent (6282). Cap and mix.
3. Use the 0.1 g measuring spoon (0699) to add one level measure of
*Phosphate Reducing Reagent (6283). Cap and mix until dissolved.
4. Wait 5 minutes for the color to develop. Insert the tube into the
Comparator (3115) and compare the color to the standards to obtain
the result in ppm Phosphate.
