ABOUT
COMPLIANCE TESTING
This DPD test system for Chlorine and Chlorine
Dioxide is accepted for reporting by most
health departments because the tests are
USEPA (DIN Standard 38 408 G4/G5, ISO
7393/2) accepted for testing requirements for Free Chlorine, Total
Chlorine, and Chlorine Dioxide.
The compliance requirement is a photometer wavelength to
measure between 490 and 530nm. The eXact iDip
®
photometer
uses a 525nm wavelength and 11 mm path-length. The
eXact
®
Strip Micro CL/Cd (DPD-1) use the same reagents and
proportions, and the resulting solution pH is maintained between
6.2 and 6.5 as specifi ed by AWWA method 4500-Cl G/ClO2-D.
The USEPA does not “approve” commercial DPD delivery
systems. The eXact
®
Strip Micro CL (DPD-1) for Free Chlorine,
and the eXact
®
Strip Micro CL (DPD-3) for Combined Chlorine,
the eXact
®
Strip Micro CL (DPD-4) for Total Chlorine, and the
eXact
®
Strip Micro Cd (DPD-1) for Chlorine Dioxide meet your
reportable testing requirements because the eXact
®
Strip Micro
strips deliver the same chemicals in identical proportions. The
eXact
®
Strip Micro Chromium is compliant because it uses the
same wavelength and delivers the same chemicals in the same
proportions as AWWA method 3500-Cr B. The eXact iDip
®
570
photometer cannot be used for compliance monitoring because
the photometer wavelength of 570nm is outside of the required
490nm–530nm range. Consult with your local Health Department for
offi cial regulations.
