Ammonia Sensor (NH₃ / NH₄⁺)

Measuring toxic and nutrient nitrogen compounds to protect health, processes, and the environment.

What Does an Ammonia Sensor Measure?

An ammonia sensor measures the concentration of ammonia (NH₃) or ammonium ions (NH₄⁺) in water or process fluids, typically expressed in mg/L or ppm. Ammonia is both a nutrient and a toxic compound, making its monitoring critical in environmental and industrial systems.

Working Principle

Ammonia sensors operate by selectively detecting ammonia molecules or ammonium ions using electrochemical, optical, or ion-selective membrane-based techniques.

Common Types of Ammonia Sensors

Signals & Outputs

Direct & Indirect Meaning of Ammonia Data

Direct Meaning

The measured value directly represents the concentration of ammonia or ammonium in a liquid.

Indirect Meaning

Ammonia trends indirectly indicate nitrification efficiency, biological treatment health, toxicity risks to aquatic life, and potential odor or safety concerns.

Industries Using Ammonia Sensors

Role of IoT in Ammonia Monitoring

With Industrial IoT integration, ammonia sensors enable real-time nitrogen load monitoring, automated treatment control, early detection of toxic conditions, and compliance-driven environmental reporting.

IndustrioPedia Perspective

The Ammonia Sensor balances necessity and danger. By controlling a vital yet toxic compound, it protects ecosystems, stabilizes treatment processes, and ensures safe industrial operations.
