This PH-303 Digital ORP and pH Controller is an upgraded version of our PH-203 Controller. It is the industrial & heavy duty version with a new re-engineered body structure. PH-303 allows you to monitor pH and ORP as well as controlling pH or ORP levels using just one unit. The large and informative display of the PH-303 is capable of displaying the status of the current conditions in the aquarium and setting values.
An ozone generation unit or ozonizers and CO2 system are control devices that regulate the amount of ozone and release carbon dioxide of the water respectively, which largely affects the pH level and filtration of the system.
This controller can be used in aquacultures, beverage, fish hatcheries, water ponds, whirlpool, spa, food processing, photography, laboratory, paper industry, swimming pool, plating industry, quality control, water conditioning, and schools.
