The determination of Hydrogen Peroxide
is one of the most important parameters for the online control
in industry. Furthermore, the observation of the oxidation
processes in industry or in waste water (e.g. to oxidise H2S) is
of high interest.
Because H2O2 is an expensive raw material, there is a
permanent demand to save money of course. This new probe system
may help here, if the hydrogen peroxide concentration is
determined continuously and insitu.
Due to high chemical reactivity of hydrogen peroxide, the
determination of H2O2 was difficult until now.
Another fact is, that analytical methods based on sampling lead
mostly to wrong results, even though the sampling and the
determination have been done very carefully.
Another point is, that the alternative volumetric titration is
very time consuming and there are permanent costs for chemicals.
A sensor or a probe system could allow the continuous reading of
the hydrogen peroxide concentration.
Titrations can only deliver average concentrations of a
well-defined volume.
Fast changes of the concentration or local concentration
gradients are only visible with in-situ sensors or probe systems.
All these disadvantages could be avoided, if the new Submersible
H2O2 Probe is used for the accurate and reliable insitu
determination in depths of up to 100 m (10 bar).
Special Features:
=> Sensors for H2O2 (amperometric
micro-sensor), temperature and depth
=> Very easy sensor exchange
=> Windows based software for display of chemical/physical
units and diagrams
=> Free selection of displayed parameters (H2O2,
temperature, depth/pressure)
=> Titanium made housing and protection cage
=> Subconn titanium connector
=> Very small dimensions (48 mm diameter, 440 mm
total length)
=> Low weight of approx. 1.1 kg
=> Low running costs for chemical sensor replacement

The Submersible H2O2 Probe is equipped
with a precision microprocessor-controlled 4-channel 16 bit analogue
to digital converter.
The data are available as RS-232 signal (multi-conductor
polyurethane covered cable) and optional as FSK signal modulated on
constant current (single-conductor cable).
The probe can be powered by battery or DC power supply (9 to 30 V DC)
when using the RS-232 output or by constant current with FSK
telemetry output (coaxial connection) for longer distances.
An interface for constant current supply is available |
