The PH-203 Controller is not only a very reliable, and highly exact pH- (0.02ph) and redox (1mV) measuring instrument with a 4-digits LCD display, but it also serves also for the regulation of the pH value and redox value in liquids e.g. water in ponds, aquarium, swimming pool, whirlpool, spa or pool etc. This controller is suitable for applications in sweet and salt-water. PH and Redox-electrode are included.
You simply set the desired pH/redox value at the controller. If the currently measured ph- or redox value increases or decreases this deviation is adjusted. This is done with the relay-steered 230V plug socket belonging to to the controller, which depending upon requirement is powered on or off. You can attach every 230V device to it e.g. air outlet stone, O3 Ozoni-sator, oxygen pump, CO2-regulator, electromagnetic valve...
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)
Carbon dioxide CO2:
in connection with a CO2-dosing system (single magnetic solenoid valve) or a CO² generator the pH value in the aquarium can be controlled and being held at a optimal level for the aquatic plants and fishes. The range of control enclosure pH values from 3,5 to 10.5 and is digitally adjustable.
