METHOD OF ANALYSIS

pH AND TEMPERATURE MEASUREMENT

ORP MEASUREMENT

The available
b r o m i n e
oxidizes the
b r o m i n e
reagents at a
pH between
5.5 and 6.0 to
form a magenta-
colored com-
pound. The
intensity of the
resulting color
is propor-
tional to the
concentration
of bromine in
the sample.
The HI 1005 pH/temperature probe provides at the out port
a potential proportional with the pH. The temperature is
measured with PT100 platinum sensor.
For increased accuracy the pH is corrected with temperature
and with the calibration coefficients. Up to 2 buffers can be
used for calibration.
The temperature can be displayed in °C or °F.
The probe can withstand pressure up to 6 bar (87 psi).
The HI 2008 probe provides at the out port a potential
proportional with the ORP value. The value is directly
displayed in mV.
The probe can withstand pressure up to 6 bar (87 psi).
