The ORP-306 "Exclusive-Line" controller is probably one of the most accurate and best redox controllers with a resolution of 1 mV with a control range of -500mV to + 500mV. It is not only a very reliable, stable and highly accurate redox meter with a 4-digit LCD display but also serves to increase the redox value of a fluid, e.g. in the electrolysis of water for ionization, drinking water treatment, water treatment for aquarium, swimming pool, whirlpool, spa or pool etc. to regulate. The meter comes fully operational and calibrated!





For regulation, the desired redox value is set on the device. If the currently measured value increases or decreases, this deviation is regulated. This is done by the relay-controlled 230V socket belonging to the controller, which is supplied with power as required or the current flow is interrupted. As a result, the device connected to it e.g. Water ionizer, air stone, O3 Ozonizer for ozone generation Oxygen pump, or any 230V device is controlled.





Example of use:
The REDOX ORP-306 Controller is a precision instrument for controlling the redox value in water in the production of ionized water, drinking water treatment, aquarium water treatment, spa, swimming pool etc.

Monitoring the ionization of water:
Water becomes ionized water after electrolysis. The redox value, which describes the antioxidant properties of a substance, provides information about its readiness to accept or donate electrons. Ionized basic water has a negative redox value of -500 mV. The water has a reducing effect and is thus considered to be an antioxidant, so it has the ability to release some of its excess electrons. The redox value of the human body is in the range of +50 to -200 mV, while the drinking water and practically all carbonated drinks have a positive redox value (oxidation) of + 150 to +250 mV.

In combination with a O3 ozonizer (available in our shop) the redox value in the aquarium can be held constantly. Sea water aquaristic is already using ozone treatment for a long time. Proven advantages are:
- Oxygenisation of the water
- Killing of alga / algae and pathogen
- Remove colored materials from the water
- Increase the effect of skimers and biological filters
- Reduction of nitrite and ammonia
- Reduction of harmful organic substances (dead plants, dead fish)


Further application:
Fish hatchery, wine production, swimming pool (bath), floristics, analysis of fluids, ponds, various industrial application, Pisciculture, Koi, Kois, Boilere, Pond, Pool, Spa, swimming pools, pool, analysis of liquids, orchids breed, breeder, hemp, grow


You get prescriptions for additional production of own variable calibration liquids for pH of values pH3 - to pH8 and electrode liquid to maintenance & keeping.
