Active chlorine and peroxide test kits

Unlike acid tests, where the focus of control is acidification level, for oxidization, the test is to verify that there is sufficient residual level at the end of the drip lateral.

As oxidization occurs throughout the irrigation system, and is subsequently “consumed” throughout the system, you need to ensure that there is sufficient concentration of oxidizer, measured in parts per million (ppm), at the end of the laterals.


“Swimming pool” type test kits are a good solution for testing residual chlorine levels.


Most test kits contain a sticker that measures the concentration of peroxide.

Note: that mg/l, and ppm are the same measurement.
