Main unit weight: 0.9 kg, including packaging weight: 1.5 kg The OZONE-AUTO-380 unit features a built-in ozone generation module, oxidation-reduction potential monitoring module, and an air pump. It continuously measures the oxidation-reduction potential (ORP) of your aquarium. When the ORP value in the aquarium falls below the ORP set value, the ozone generation module activates automatically, continuously producing ozone until the ORP value reaches the ORP set point. The OZONE-AUTO-380 unit offers parameter display and functional operation through a touch screen LCD. It intuitively presents ozone output value, ORP set value, ORP reading, ozone output LED indicators, and selection indication for internal or external pumps. Using the touchscreen LCD, you can control the ozone value (0-100%,0-380mg/h), set the ORP set value(0-4500mV), choose between internal or external pump options, and select the ozone output mode. There are three ozone output modes: OZONE AUTO: Automatically generates ozone based on the ORP set value and ORP reading (If ORP reading < ORP set value, ozone output activates; otherwise, ozone output turns off). OZONE ON: Always turns on ozone output. OZONE OFF: Always turns off ozone output. Package included: Main unit*1, Power adapter (12V/2A)*1, Air dryer (200mL)*1, ORP probe*1, Silicone hose*2 meters, Air stone*2
