redox reaction is a chemical reaction consisting of of the partreaktions
oxidation and reduction. With our portable measuring instrument
ORP-169A, you can simply measure fast, precisely and comfortably
the redox potential of your aquarium, pond, spa or pools.
can be used in the sea water aquarium for the controlling of
an ozone addition as well as in sea and fresh water basins for
the controlling of the nitrate dismantling in anaerobic biological
filters. Ideally also to the indirect chlorine measurement in
the swimming pool and pool.
redox tension a measuring method for the water quality
The redox tension is indicated in mV and describes the oxidizing
or reducing character of a medium out. In principle the more
highly the redox value applies, the more unloaded is the water.
The continuous reduction of the redox value indicates, that
an unwanted biological process runs off e.g.
In the water treatment the redox measurement comes in particular
in the context of the decontamination to the reduction of chromate
or oxidizing from cyanide to application as well as the monitoring
of the disinfection effect during oxidizing agent dosage.
Within the swimming pool range one uses the redox measurement
for the determination of the sterilization ability of the water.
For example the time the swimming pool water needs to kill e-koli-bacteria
depends on the redox value, which means of the operational readiness
level from free chlorine. The necessary value is with approx.
In the fresh water aquarium 250 mVs are already completely good,
higher values better. In the sea water it should be 350 to 400
mVs. The reduction and oxidation process in the aquarium take
place within living cells. Here there are fish, plants and bacteria
who determine the metabolism of the aquarium.
The result of the redox measurement means, whether the pond
water is organically loaded or not. It informs about the condition
of oxidation. If the redox potential of the pond water is between
150 and 450 mVs, a quality statement is not possible with a
individual measuring. The change of the values from a series
of measurements over a longer time interval possesses a higher
force of statement (sinking values mean increased organic load,
rising values signal a condition improvement). Redox values
under 150 mVs signal a high organic load, Values over 450 mVs
leave conclusions on oxidizing agent (chlorine, wash and detergent).
