Total Fluoride Analyzer – CA900

The ECD CA900 Fluoride Analyzer is an all-in-one analyzer for the
continuous measurement of fluoride concentration in aqueous
media. Applications include drinking water effluent, industrial
waste water, semi-conductor manufacturing and wastewater
discharge compliance.
The CA900 Fluoride Analyzer are easy to start up and use, simply
connect the sample, waste and reagent lines and then power up
the factory calibrated analyzer. Wall mounting hardware is
standard but and optional benchtop stand is also available.
Accessing information or customizing an analysis routine are
easily accomplished with the simple, user friendly menu structure
and large color touch screen interface.
The analyzer has two separated enclosures with lockable doors.
The top enclosure, called the ELECTRICAL enclosure, includes the
main power supply, the controller PCB assembly, and the touch
screen interface. The bottom enclosure, called the LIQUIDS
enclosure, includes all the components involved in the sample
and reagent flow, mixing, and measurement.
The fluoride measurement is based on ECD industrial grade ion selective
electrode technology. The analyzer mixing chamber
contains ECD fluoride ion and pH electrodes for the
measurement. The analyzer uses TISAB reagent for an ionic strength adjustment to the sample to be measured, which breaks
weak complexes formed with fluoride and certain metals such as
aluminum or Iron (+3), to provide the fluoride concentration
measurement. Additionally, the analyzer utilizes a pH
compensation technique to provide accurate fluoride
measurement in varying pH ranges. The CA900 Fluoride Analyzer
has a configurable automatic calibration feature utilizing fluoride
calibration standards that can be programmed for routine
calibration cycles.
The CA900 Fluoride Analyzers is powered by 100 – 230 VAC,
provides (4) 4 to 20 mA outputs, (4) configurable relays, serial
output and can be web enables for remote access.
The ECD CA900 is easy to start up and maintain. First connect the
Sample feed line, reagent lines and Drain line to the analyzer.
Mount the sensors in the flow cell. Next connect the outputs,
and supply power, a switched 110/220 VAC line. Prime the
peristaltic pumps and start the measurement cycle. The touch
screen display and 4-20 mA outputs will indicate the fluoride
concentration. A digital display indicates the measurement and
the 4-20 mA output values are captured in the measurement
cycle and displayed until the next measurement cycle.
Configurable relays provide remote user alarms and control.
