Range of application

IMPORTANT
• Non-compliance with operating conditions specified in
the technical data (see section 14) could lead to a measur-
ing error and to a dangerous over metering within a closed
loop.
• The sensor is not suitable for checking for the absence of

The DULCOTEST
amperometric sensor for the online determination of the
concentration of hydrogen peroxide. Hydrogen peroxide serves
a.o. as bio-degradable disinfection and oxidation agent. The
sensor can a.o. be used in the following applications:
• Oxidation of drinking water, landfill leachate, contaminated ground
water
• Disinfection of cooling, service, and production water in the
pharmaceutical, food and beverages industry as well as in
swimming pools
• Deodorization (gas scrubber) in municipal and industrial purifica-
tion plants
• Dechlorination in chemical processes
• Chemical bleaching in the timber, paper, textile and mineral
materials industry
• Organic synthesis in the chemical, pharmaceutical, and cosmetics
industry

the electrode shaft and the diaphragm cap (see fig. 1). The
electrolyte-filled diaphragm cap represents the measuring chamber
into which the measuring electrodes are immersed.
The measuring medium is sealed by a diaphragm in the measuring
chamber.
The electronic amplifier is embedded in a synthetic compound in
the upper section of the shaft.
The sensor has a passive 4-20 mA two-wire interface. Power is
supplied externally from a measuring and control system, e.g.
