STRIP MICRO CL INTERFERENCES
Interfering Substance Interfering Levels and Treatments
Acidity If sample has acidity above 150mg/L CaCO3
test may not develop full color. Neutralize to
pH 6.0 to 7.0 with 0.5N Sodium hydroxide.
Alkalinity
If sample has alkalinity above 200mg/L CaCO3
test may not develop full color. Neutralize to pH
6.0 to 7.0 with 0.5N Sulfuric acid.
Bromine and Bromamines, Br
2
Color similar to free chlorine reaction at all levels.
Chlorine Dioxide, ClO
2
Color similar to free chlorine reaction at all levels.
Copper, Cu
2+
Color development is reduced above 10 ppm (mg/L).
Iodine, I
2
Color similar to free chlorine reaction at all levels.
Manganese, oxidized (Mn
4+
, Mn
7+
)
or Chromium, oxidized (Cr
6+
)
See AWWA procedure 4500-CL F, 1(d) for
removal of interferences.
Monochloramines (NH2Cl)
(applies to DPD-1 only)
Monochloramine interferences are known
to occur in free chlorine DPD methods. This
interference is dependent on temperature and
monochloramine concentration.
Ozone, O
3
Color similar to free chlorine reaction at all levels.
Peroxides Interference is possible.
pH
Typical pH samples of potable water with a pH
of 6.0 to 9.0 are OK. If outside this range adjust
to pH 6.0 to 7.0 using acid (0.5N Sulfuric acid)
or base
(0.5N Sodium hydroxide).

SMART TECHNOLOGY
Bluetooth
®
SMART is a low-power networking standard
which uses short radio waves to allow electronic devices
to communicate with each other wirelessly. The eXact iDip
®
comes standard with the latest Bluetooth
®
4.0 technology
(bluetooth.com/Pages/Bluetooth-Smart.aspx). It is a class
2 device with a wireless working distance of up to 30 feet
(10 meters) and a 2.1 Mbps data transfer rate. This allows a
seamless transfer of data between a smart device and the
eXact iDip
®
.
BUILT IN SAMPLE CELL
The built-in sample cell is made of transparent plastic;
the sturdy cell design will last for over 20,000 readings.
Our studies have shown that scratches on the cell will not
compromise the accuracy of your results because of the
cell’s fi xed position.
MAKING CALLS
The eXact iDip
®
photometer is not intended for use while
talking on your smart phone. Talking during testing may
cause the app to shutdown.
