Range 0 - 100 mg/l (ppm)
Method: Indicator
Yellow - Green - Blue
PHMB is the generic name for various polybiguanide-based swimming pool
biocides. These biocides are normally sold under branded product names, for
example Baquacil* (Zeneca), Softswim* (Biolab), Revacil* (Mareva) and
Nicosil* (NICO Norge).
Commercial products normally contain 20% active PHMB. This test has been
calibrated for the management of pools using commercial products of this
strength. A factor will need to be applied if products of a different strength are
being used.
