Description
The Residual Chlorine test strip is for use in ensuring free chlorine levels in drinking water are sufficient to inactivate some hazards, as well as ensuring the water is protected from re-contamination during storage. The strip can also be used to ensure systems have no residual free chlorine after chemical sanitization by testing for very low levels of free chlorine in solution from 0.0 ppm – 5.0 ppm.
Instructions for use:
Dip the test strip directly into water.
With the test pad in the water, move back and forth 2 times per second for 5 seconds.
Remove the test strip, and compare to the color chart within 5 minutes.
