3 PLUS RESIDUAL ANALYZER
INTRODUCTION
The Depolox 3 plus Residual Analyzer is a low, cost economical analyzer
for potable water that continuously measures either free or total chlorine,
chlorine dioxide or ozone residuals using proven amperometric measure-
ment technology. There is also an arrangement available for measuring
pH or flouride.
The Depolox 3 plus analyzer consists of two separate components: a “wet
side” package containing the sensor/cell and an electronic control pack-
age.
The electronic package is available for either 115 or 230 volt operation.
A single input arrangement is used when only a disinfectant measurement
(free or total chlorine, chlorine dioxide, ozone) is required. A dual input
arrangement is available when either pH or fluoride measurement is re-
quired in addition to a disinfectant measurement. Note that for pH- or
fluoride-only measurement, the dual input electronic package is required
and the dual input cannot be used for two disinfectant measurements. The
electronic package provides for operator input via plain-text-assisted,
self-explanatory menus and a sealed keypad. The large, two-line (16
characters each) display of disinfectant residual alternates every five
seconds with the pH or fluoride values when the analyzer is set up for two
measurements.
There are two wetside configurations available: Membrane and Bare
Electrode. Both consist of a flow-through cell with a transparent plexiglass
body that houses one or two measuring sensors. The cell’s transparency
permits visual checks on the flow of sample water and measuring condi-
tions. The Membrane wetside can be fitted with any one of four mem-
brane-type sensors (free chlorine, total chlorine, chlorine dioxide or ozone)
for disinfectant measurement. A second sensor can be added for pH or
fluoride measurement. The bare electrode wetside is available for free
chlorine measurement only. This arrangement can be used where a quick
response time is required or if there is a high hardness in the sample water
that could foul a membrane sensor. A second sensor can be added for pH
or fluoride measurement. Note that free chlorine measurement by this
wetside is affected by changes in pH. An optional CO2 gas reagent kit is
available for economical pH adjustment. It is also possible to compensate
for pH changes by using a dual input arrangement with the pH sensor
option for automatically calculating the residual value.
