Ammonia sensors and detectors play a critical role in protecting people, infrastructure, and processes across industries where ammonia (NH₃) is used, stored, or produced. ProDetec supplies high-performance ammonia gas detector solutions designed for early leak detection, worker safety, and regulatory compliance across Australia.
Ammonia is widely used in industrial refrigeration, cold storage, agriculture, fertiliser production, and chemical manufacturing. While highly effective as a refrigerant and process gas, ammonia is also toxic and corrosive at elevated concentrations. Reliable ammonia sensor technology ensures leaks are detected quickly – before they escalate into serious safety, environmental, or operational incidents.
With over 20 years of experience delivering gas detection systems, ProDetec combines globally proven technology with local Australian support, calibration services, and engineering expertise to deliver dependable ammonia detector solutions for fixed and portable applications.
An ammonia gas detector is a specialised gas detection device designed to measure the concentration of ammonia in the air or within industrial processes. These devices continuously monitor ammonia levels and trigger alarms when concentrations exceed safe thresholds.
Ammonia has a distinctive pungent odour, often detectable at very low concentrations. However, repeated exposure can rapidly dull the sense of smell, meaning workers may no longer notice ammonia even when levels become dangerous. This makes reliance on human senses unreliable and reinforces the need for engineered ammonia detection systems.
Most industrial ammonia sensors use electrochemical sensing technology. NH₃ molecules “dock” on the surface of the sensor, causing charge carriers to be injected into the sensing element. This results in a change in electrical current or resistance that is directly proportional to the ammonia concentration present in the air.
High-quality ammonia detectors provide:
Different applications require different ammonia detection technologies. ProDetec supplies a range of ammonia sensor solutions selected for accuracy, durability, and suitability for Australian conditions.
Electrochemical ammonia sensors are the most common technology used for NH₃ detection. These sensors offer high sensitivity and accuracy at low ppm levels, making them ideal for occupational safety monitoring.
One limitation of electrochemical sensors is cross-sensitivity to other gases, which is managed through proper sensor selection and calibration.
Semiconductor (MOS) sensors are sometimes used in lower-cost or portable ammonia detectors. These sensors are robust but generally less selective than electrochemical options.
Electrochemical sensors remain the industry standard for fixed systems.
Ammonia detection in Australia is governed by strict safety and compliance requirements. ProDetec’s ammonia detection solutions are designed to support adherence to key standards and guidelines, including:

Ammonia detectors should typically be calibrated atleast every 6 months, depending on site conditions, exposure levels, and manufacturer recommendations.
Most electrochemical ammonia sensors have a lifespan of 2-5 years. Environmental conditions and exposure frequency can affect longevity.
Yes. Modern ammonia gas detector systems can integrate with BMS, SCADA, and safety PLCs for alarms, ventilation control, and shutdown functions.
Common alarm setpoints include 25 ppm (TWA), 35 ppm (STEL), and 300 ppm (IDLH), aligned with Australian safety guidelines.
