ATEQ’s Differential Noise Cancelling (DNC) technology filters out unwanted disturbances in real time. By isolating only the true pressure variation caused by an actual leak, DNC ensures reliable and repeatable measurements, even in harsh production conditions.

The result is faster cycle times, fewer false rejects, and higher testing consistency, perfect for demanding manufacturing environments.

When combined with the ATEQ F620 Large Volume Differential Pressure Decay Leak Tester, the DNC feature helps detect pressure drops as small as 0.04 Pa/sec, even when the environment is unstable.

1. Stabilizes results by removing background noise
2. Reduces retests and improves production flow
3. Enhances measurement accuracy and repeatability

Environmental factors can influence pressure readings during a test. The DNC system compensates for these variables:

Pressure fluctuations – caused by ventilation systems or building airflow

Temperature variations – due to HVAC cycles or weather changes

Airflow changes – from fans or doors opening nearby

Vibrations – from conveyors, forklifts, or nearby machinery
