PH-803 DIGITAL PH ORP (2 in 1) CONTROLLER + ELECTRODES + CO2 & O3 Relay 110V/220V


Model: PH-803  


Our PH-803 is most advanced type of CONTROLLER with which it can simultaneously measure and display the pH value and redox value (ORP) as well as the other all at the same time which is contrary to almost all other PH/ORP controller. It has 2 BNC electrodes (pH and redox) that you can easily replace anytime, 2 circuits and 2 switched sockets.You can simultaneously control your CO²-plant (via pH value) and an ozoniser (via orp value) at the same time. PH-803 also allows you to control or operate 1 value at time, if necessary, you can operate the equipment with only pH value or just the redox value. Simply set the desired pH/redox values in the controller. If the currently measured pH or Redox value increases or decreases this deviation is adjusted. This can be done with the relay-steered 110V/220V plug socket of the controller. You can attach every 110V/220V device to it like air outlet stone, O3 ozoniser, oxygen pump, CO2-regulator, electromagnetic valve and other ORP & pH control devices.


Applications & Usage:

Fish hatchery, wine production, swimming pool (bath), laboratories, water conditioning, schools & colleges, floristics, for analysis of fluids (ph-value), ponds, various industrial application, Pisciculture, Koi, Kois, Boilere, Pond, Pool, Spa, swimming pools, pool, analysis of liquids, orchids breed, breeder, hemp, grow, etc.The suitable way for you to keep an eye on the different water parameters in your tank! A MUST to have a perfect way to automate 7 regulate the control devices in your aquarium to ELIMINATES FATALITY and MAINTAIN a HEALTHY WATER SYSTEM!!
