How to choose a pH probe
A pH probe and a pH sensor are the same instrument: the electrode that is immersed in the water or mounted in a pipe. The Agrinovo range splits by output signal first and by the liquid second. Start from what will read the probe, then check the process conditions.
| Model | Output | Range and accuracy | Choose it for |
|---|---|---|---|
| PH-100 | RS485 Modbus RTU | 0.00 to 14.00 pH, ±0.02 pH | Freshwater monitoring with a digital signal |
| PH-110 | RS485 Modbus RTU or analog (0-2 V, 0-5 V, 0-10 V, 4-20 mA), chosen at order | 0 to 14.00 pH, ±0.02 pH | Seawater, and controllers or PLCs that need an analog input |
| PH-10 | Analog | -2.00 to 16.00 pH, ±0.01 pH | In-line mounting (PG13.5 thread) on an existing pH transmitter |
| PH-G10 | Analog | -2.00 to 16.00 pH, ±0.01 pH | Hot liquids, 0 to 110°C |
| PH-T10 | Analog | -2.00 to 16.00 pH, ±0.01 pH | Flue gas desulfurization lines |
Digital or analog
A digital pH probe converts the signal inside the probe and sends a finished reading over RS485, so cable length and electrical noise matter far less and several probes can share one cable. An analog pH electrode sends the raw electrode signal and needs a transmitter or controller input built for it.
All five are rated IP68. The digital models connect to an Omni Genesis controller with other water quality sensors on the same bus. For the trade-offs in detail, read the RS485 pH sensor selection guide.
