PH-803 is a professional 2-in-1 PH and ORP integrated controller, supporting simultaneous real-time monitoring of PH value and ORP redox potential. Equipped with dual digital LED display, measurement data can be viewed clearly at a glance.

It supports two-point PH calibration with PH4 and PH7 buffer solutions. Users can set high/low threshold values for PH and ORP separately. The device triggers automatic output control to drive solenoid valves or dosing pumps to adjust water quality.

Built-in independent alarm reminders for PH and ORP. Compact wall-mounted design suits long-term continuous monitoring. Widely used in aquariums, aquaculture, swimming pools, hydroponics and water disinfection systems, helping you maintain a stable aquatic environment.
