1. **Resistance Reduction**: Small curvature elbows reduce the resistance of the airflow as it passes through compared to sharp turns, thus maintaining high sampling efficiency.
2. **Deposition Reduction**: The smooth curved design helps to minimize the deposition of particulate matter inside the elbow, ensuring accurate sampling.
3. **Material Selection**: The material of the elbow should be selected according to the sampling environment, commonly stainless steel, glass and plastics. to avoid contamination of the sample.
4. **Cleaning and Maintenance**: Since dust or other particles tend to accumulate inside the elbow, regular cleaning is necessary.
In specific applications, it is also necessary to select the appropriate elbow type and size according to the actual sampling requirements and environmental conditions.
Small curvature elbows in air sampling tubes are commonly used in airflow paths to change the direction of airflow. There are several key points to consider when de…
