How to choose a conductivity sensor
A conductivity sensor, an EC sensor and an EC probe are the same instrument: two electrodes that measure how well water carries current. Salinity and TDS are calculated from that reading. The Agrinovo range splits by three things: how conductive the water is, what the water does to the probe body, and what will read the signal.
| Model | Output | Range | Body or electrode | Choose it for |
|---|---|---|---|---|
| EC-100 | RS485 Modbus RTU | 0.2 µS/cm to 100 mS/cm (by cell constant) | Two-graphite electrode | Freshwater, groundwater, irrigation and general use |
| EC-110 | RS485 Modbus RTU | 0 to 200 mS/cm, salinity 0 to 100 ppt | Two-graphite electrode, PTFE housing | Seawater and brine, with salinity and TDS reported directly |
| EC-120 | RS485 Modbus RTU | 0 to 200 mS/cm, salinity 0 to 100 ppt | Graphite electrode, PTFE body | Seawater, brine and acid or alkali solutions, with float output in engineering units |
| EC-J100 | RS485 Modbus RTU | 10 µS/cm to 200 mS/cm | Fluoropolymer and titanium | Seawater, hot or corrosive liquids, chemicals |
| EC-10 | Analog | 1 to 2,000 µS/cm | Plastic shell | Tap water, groundwater and wastewater on an existing transmitter |
| EC-GS10 | Analog | 0.01 to 2,000 µS/cm (by cell constant) | 316L stainless steel | Ultra-pure water through to process water |
| EC-J10 | Analog | 1 µS/cm to 200 mS/cm | PVDF | Seawater, hot or corrosive liquids on an existing transmitter |
The cell constant sets the range
Every conductivity probe has a cell constant, K, fixed by the geometry of its electrodes. A low constant (K=0.1 or K=0.01) reads very pure water accurately. K=1 covers ordinary fresh water. K=10 reaches the high readings of seawater and brine, up to 200 mS/cm on the EC-110, EC-J10 and EC-J100.
The EC-100 is ordered with K=0.1, 1.0 or 10.0, and the EC-GS10 with K=1, 0.1 or 0.01, so tell us the expected conductivity when you ask for a quote.
Digital or analog
The digital models convert the measurement inside the probe and send conductivity and temperature over RS485 Modbus RTU, with automatic temperature compensation. They connect to an Omni Genesis controller on the same bus as other water quality sensors. The analog models send the raw electrode signal and need a conductivity transmitter.
