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
(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
.

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 fixed position.

Interfering Levels and Treatments
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.
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.
Color similar to free chlorine reaction at all levels.

Monochloramine interferences are known
to occur in free chlorine DPD methods. This
interference is dependent on temperature and
monochloramine concentration.
Color similar to free chlorine reaction at all levels.
Interference is possible.
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).
