Ammonium ion selective electrode + probe

Ammonium ISE

Our Single ION model, with a BNC connector, offers a reliable, high-performance ammonium electrode designed for precise ion measurements. It’s compatible with most lab ion meters equipment and easy to use.

The system includes a mini ammonium sensor with a replaceable tip, allowing quick changes with compatible tips from our catalog. This design extends the electrode’s life and reduces maintenance costs.

NT Sensors’ solid-state ISEs offer fast, reliable ammonium readings with sensitivity and selectivity on par with other ISEs, making them ideal for environmental monitoring, water treatment, and aquaculture.

With nanotechnology, we deliver high-quality, cost-effective ISE solutions. All our products are proudly designed and manufactured in Spain, Europe.

IMPORTANT NOTE: Calibration standards are essential for creating the calibration curve in ammonium ion sensors.

The ammonium ISE + probe is a half-cell ion-selective electrode (ISE) .

This electrode features a sensor tip module built with a polymer membrane containing a specialized ammonium ionophore, designed specifically for selective ammonium ion detection in aqueous solutions. Each sensor module is color-coded to match probe module slots, ensuring quick identification and easy replacement. The probe’s mini electrode is replaceable, pressure-sealed connection design facilitates a fast and secure setup.

The ammonium-selective electrode accurately measures ammonium ions, which coexist in equilibrium with ammonia in solution. Since this equilibrium is sensitive to pH and temperature, simultaneous pH and ammonium measurements are recommended for precise monitoring. High ammonium levels can negatively impact ecosystems, drinking water, and aquaculture, making continuous ammonium monitoring crucial.

Typical Applications for Ammonium Monitoring:

  • Environmental water quality testing
  • Drinking water treatment facilities
  • Aquaculture and fisheries
  • Agricultural runoff and fertilizer management

Regular ammonium monitoring is key to protecting water quality and ensuring the health of aquatic environments.

Note: This electrode requires a separate reference electrode for accurate operation.
