Digital Air Permeability Tester NADPT-100 – Material Airflow Measurement Equipment

What is Digital Air Permeability Tester NADPT-100?

Digital Air Permeability Tester NADPT-100 is a laboratory instrument used to measure how easily air passes through materials under controlled pressure conditions.

It provides accurate airflow measurements to evaluate porosity, breathability, and structural consistency.

What Does Digital Air Permeability Tester NADPT-100 Measure?

The instrument measures:

• Airflow rate through material

• Pressure differential across sample

• Air permeability value

These results help assess material performance in industrial and research applications.

How Does Digital Air Permeability Tester NADPT-100 Work? 

1. Material sample is placed in the test chamber

2. Sample is clamped securely

3. Controlled pressure is applied

4. Air flows through the sample

5. Sensors measure airflow rate

6. System calculates and displays permeability

Higher airflow = higher permeability
Lower airflow = denser material
