A 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.

It 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.

The 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. dead fish).

Industrial waste water
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.

Swimming pool
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. 700 mVs.

Aquaristic
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.

Ponds:
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).
