Water Quality Sensors

Hydrolab Ammonium

The Hydrolab Ammonium Sensor is a precision ion-selective electrode (ISE) designed for accurate ammonium (NH₄⁺) measurement in professional water quality monitoring applications. Ammonium is a key indicator of nutrient loading, wastewater influence, and biological activity, making the Hydrolab Ammonium sensor essential for environmental monitoring and water quality management.

Factory integrated into the Hydrolab HL4 and Hydrolab HL7 multiparameter water quality meters, the Hydrolab Ammonium sensor delivers reliable, real-time ammonium measurements in rivers, streams, lakes, groundwater, and wastewater systems. Its robust design and proven sensing technology ensure dependable performance in both routine field surveys and long-term unattended monitoring deployments.

WHY MEASURE AMMONIUM?

Ammonium is a critical indicator of nutrient pollution and wastewater influence in aquatic systems. Elevated ammonium concentrations can be toxic to aquatic life and often signal recent contamination from sewage, agricultural runoff, or industrial discharges. Monitoring ammonium levels helps identify pollution sources, assess treatment performance, and protect environmental and public health.

The Hydrolab Ammonium sensor provides timely, reliable ammonium data that supports informed decision-making in environmental monitoring, wastewater management, and water quality protection programs. When combined with other Hydrolab sensors, ammonium measurements contribute to a comprehensive understanding of nutrient dynamics and system health.

IMPORTANT

Note: The Hydrolab Ammonium Sensor is supplied as a factory-integrated accessory and cannot be purchased as a standalone product.
