How to choose a dissolved oxygen sensor
Every Agrinovo dissolved oxygen sensor on this page uses fluorescence (optical) measurement and reports over RS485 Modbus RTU. The measurement is the same across the range. What changes is the body material and the cleaning, so the choice comes down to the water the probe will sit in.
| Model | Body | Range | Output | Choose it for |
|---|---|---|---|---|
| DO-100 | 316L stainless steel | 0-20 mg/L, 0-200% saturation | RS485 Modbus RTU | Freshwater ponds, tanks and RAS |
| DO-110 | Titanium alloy | 0-20 mg/L, 0-200% saturation | RS485 Modbus RTU | Seawater and marine systems |
| DO-P100 | PE (polyethylene) | 0-20 mg/L, 0-200% saturation | RS485 Modbus RTU | A polymer body, water at 0-40°C |
| DO-130 | Automatic cleaning brush | DO in mg/L plus temperature | RS485 Modbus RTU | Very dirty water or heavy algae |
Fixed probe or handheld meter
A fixed dissolved oxygen probe stays in the water and reports around the clock, which is what catches a night-time oxygen drop. A handheld dissolved oxygen meter is for spot checks across many ponds or tanks. For that job see the portable dissolved oxygen meter, which reads on a phone and logs each measurement.
The fixed probes connect to an Omni Genesis controller alongside pH, conductivity and temperature sensors, so one controller covers a pond or a tank group. The full selection logic is in the dissolved oxygen sensor guide for fish farming.
