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 specified 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
official regulations.
