Highlights
The Dräger Polytron A500 is a transmitter designed for long-term measurement of ammonia in environments with high humidity and/or dust levels. The special convection cap protects the associated electrochemical DrägerSensor NH3 FL against external influences and ensures continuous NH3 measurement under the specific conditions present in raw and clean gas in exhaust air scrubbing systems.
Durable sensor design enables continuous ammonia measurement in exhaust air
The Dräger Polytron A500 is especially resilient when used in the demanding conditions found in exhaust air treatment systems/air scrubbers or similar end-of-pipe scenarios. The convection cap with integrated heating enables the long-term stable Dräg … More information
erSensor NH3 FL to deliver accurate, drift-free measurements, even with temperature fluctuations, humid ambient air with up to 100% relative humidity, corrosive spray mist, high velocity airflow and heavy dust exposure. The sensor is highly stable over time, eliminating the need for recalibration.Precise real-time measurements with high resolution
The DrägerSensor NH3 FL measures ammonia in the 0 – 50 ppm range with high precision and a resolution of 0.15 ppm. The Polytron A500 sensor head outputs a real-time signal via its analogue interface, either 0 – 10 V or 4…20 mA. This allows the device … More information
to be connected to standard evaluation units, data loggers and control systems used in exhaust air treatment plants.Simple installation and low maintenance
The Polytron A500 is suitable for a wide range of air cleaning system types. It is installed directly within the system. The hanging bracket ensures the transmitter is positioned vertically, allowing the sensor to perform optimally. The Polytron A500 … More information
also indicates when the sensor needs replacing. Between replacements, the transmitter is maintenance-free. This makes it suitable for a wide range of quality-assured measurement tasks.Measuring separation efficiency with a dual-sensor setup
Using two Polytron A500 units makes it possible to continuously monitor the difference between raw gas and clean gas concentrations at the measurement site. To do this, one Polytron A500 with ammonia sensor is placed in the raw gas flow or upstream o … More information
f the first filtration stage, and the other in the clean gas stream after the last relevant filter stage. This provides a clear indication of the system's separation efficiency, and enables direct monitoring of NH3 reduction.Optimising exhaust air cleaning system operation using measured emissions data
The Polytron A500 supports the monitoring and control of both performance and efficiency in existing and new air cleaning systems. It delivers real-time data that helps you optimise operating parameters while controlling ammonia emissions.
