tubing attached. Before starting up the instrument, verify that
the tubing lines are secured.
TRO measurement sensing electrode
The TRO measurement electrode is a combination style
electrode consisting of a platinum sensing element and an
iodide reference element. A differential potential is developed
across these elements relative to the presence and
concentration of iodine in the sample stream. This potential
difference signal read by the analyzer in the form of a millivolt
signal which is then processed to obtain the TRO
concentration.
Automatic Temperature
Compensation (ATC)
The temperature sensor is integrated into the TRO Flow Cell
and is a resistive element type sensor (30 Kohm thermistor).
The temperature signal is passed to the analyzer to provide
the sample stream temperature. Automatic compensation
software adjusts the resulting measurement to reflect the
value which would result if the sample was at calibration
temperature.
Reagent
A TRO reagent is used to enhance and stabilize the
measurement in a variety of Dissolved Organic Carbon (DOC),
Particulate Organic Carbon (POC) and slit conditions found in
different cooling water matrix. The reagent is easily installed or
replaced with quick connect tube connector and is replaced
after approximate 80 hours of active chlorinating or
discharging operations.
