Reagent-free nitrate ion-selective sensor with optional NH4+, K+, Ca2+, and other ion membranes plus RS485 / Modbus output.
AquaSense-NO3 is the ion-selective electrode (ISE) version of the AquaSense family. It is factory-configurable for nitrate as the default channel — and, on order, for ammonium (NH4+), potassium (K+), calcium (Ca2+), and other common environmental ions — making it a flexible reagent-free tool for nutrient and ion monitoring.
Configurable for NO3-, NH4+, K+, Ca2+ and similar ions on order.
ISE measurement avoids consumables and chemical waste.
Supports user-defined standards with forward / reverse curve.
Submersible body for in-situ deployment in tanks and natural water.
Long-life industrial-grade electrode for continuous online operation.
Built-in NTC temperature sensor with automatic compensation.
Digital RS485 output with Modbus RTU protocol for networked deployments.
Isolated power-supply design improves data stability and noise immunity.
Submersible body for direct insertion into pipes, tanks, and natural water.
Stable electrochemistry with simple field calibration workflow.
AquaSense-NO3 is the ion-selective version of the AquaSense water-quality family. With nitrate (NO3-) as the default channel, it can also be ordered with NH4+, K+, Ca2+, and other common environmental ion-selective membranes — making it a flexible single-platform tool for surface water, drinking water, and wastewater monitoring. The reagent-free design avoids consumables and chemical waste.
The sensor supports custom calibration with user-supplied standard solutions and can be configured with either forward or reverse calibration curves. An isolated power-supply architecture provides strong data stability, and the RS485 / Modbus RTU interface integrates directly into existing telemetry and SCADA systems.
