 Download BrochureProduct Description
The APM433N Gaseous Pollutant Sampler is designed for accurate and controlled sampling of gaseous pollutants using an impinger-based sampling train. The system incorporates a manifold with four inlets and one outlet, allowing controlled airflow through multiple sampling paths. Each inlet is equipped with a built-in needle valve, enabling independent adjustment of flow rates for precise sampling.
The sampling rate of each impinger is monitored using a rotameter, ensuring consistent airflow throughout the sampling process. With a maximum sampling time of up to 24 hours, the APM433N supports long-duration monitoring requirements commonly used in ambient air quality studies.
The integrated 0–3 LPM rotameter allows easy visual verification and adjustment of flow rates during operation. Housed in a durable enclosure, the sampler is suitable for both field deployment and laboratory environments, making it a practical solution for routine gaseous pollutant monitoring applications.
