Reagent-free ion-selective ammonium sensor with isolated power, custom calibration, and RS485 / Modbus output for water monitoring.
AquaSense-NH4 is an environmentally friendly, reagent-free ion-selective sensor designed for ammonium monitoring across surface water, drinking water, and wastewater. The submersible body supports direct in-situ deployment, and an isolated power-supply architecture delivers stable readings under noisy electrical conditions.
Ion-selective electrode removes the need for chemicals or kits.
Support for custom standard solutions and forward / reverse curves.
Submersible body for direct deployment in tanks, channels, and natural water.
Isolated design improves data stability and noise immunity.
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-NH4 is a reagent-free ion-selective ammonium sensor for nutrient monitoring in fresh water, drinking water, and wastewater. The environmentally friendly design avoids consumables and chemical waste, and the submersible body supports direct deployment in tanks, channels, sondes, and natural water bodies.
The sensor supports custom calibration with user-supplied standard solutions and can be configured with either forward or reverse calibration curves to suit the local application. An isolated power-supply architecture provides strong data stability and immunity to electrical noise, while the RS485 / Modbus RTU output makes integration into existing telemetry straightforward.
