Code: DEPOLOX® 5 bare
Product name: DEPOLOX® 5 bare electrode for Cl2, O3, ClO2 or KMnO4 measurement

The DEPOLOX® 5 measurement module can be used with either the SFC electronic package for single point analysis and control or the versatile MFC electronic package for multiple measurements and control.

  General
The DEPOLOX® 5 measurement module can be used
with either the SFC electronic package for single
point analysis and control or the versatile MFC
electronic package for multiple measurements and
control. It consists of a plug-in sensor card and flow
cell with an integral, bare-electrode measurement
configuration. Utilizing amperometric residual
measurement technology, it is suitable for disinfection
applications, ranging from simple measuring/
monitoring tasks to complex control processes for
treating potable water, process water, and pool
water. The DEPOLOX® 5 flow cell has a standard
measuring range from 0.01 to 200 mg/l of free
chlorine.

Typical applications

•  Measurement and control tasks in potable water
• works and by potable water suppliers
• Process water monitoring in all water-based industrial processes
• Cooling water monitoring

Features
The DEPOLOX® 5 flow cell consists of a 3-electrode
system utilizing a bare-electrode design which provides
a quick response time (90 % change < 20 sec.)
with high accuracy (±2 % F.S.) when compared to
membrane sensor technology. Hydrodynamic grit
cleaning of the electrode surfaces maintains sensitivity
to extend the intervals between calibrations.
Zero point calibration is not necessary. A sample with
a constant pH is required, however, the addition of a
pH sensor can provide for compensated free chlorine
measurement with the suitable electronic package.
An integral multi-sensor provides a PT 1000 temperature
measurement and monitors sample flow to
provide a loss-of-flow alarm contact. The flow cell is
supplied with a 1 m (3.3 ft.) screened coaxial cable.
Up to three additional sensors can be fitted into the
flow cell for measuring other water parameters.
Utilizing “plug and play” technology allows the SFC
or MFC controller to automatically recognize the
sensor card and provide the correct display
information. An analog output (0/4 to 20 mA) is
available along with user configurable alarm contacts.

Benefits:

• Accurate measurement and high reproducibility
• Fast response time to meet fluctuating disinfection demands
• Rugged design and minimal maintenance due to hydrodynamic cell cleaning
• Economical, reagentless operation
• Proven operation in thousands of installations around the world
• Intuitive programming for user-friendly operation
