Description

Mid level chlorine test strips measure residual chlorine from 0-300 ppm in increments of 0, 25, 50, 100, 200 and 300 ppm in just seconds.
This test strip produces a distinct colour change over the entire range from blue to brown to orange.
The strip can also be used to test for chlorine during disinfection processes.

Instructions:

• Immerse the test strip in the sample and remove immediately.
• Hold strip level (do not shake off excess sample).
• Compare to the color chart between 5 and 10 seconds after removing the strip from the sample.
