Core Diagnostic Capabilities

High-Sensitivity Leak Detection: Identifies pressurized gas and vacuum leaks with a minimum detection threshold of >0.0032 L/min from a distance of 2.5 meters.

Mechanical Fault Identification: Supports the detection of mechanical noise, allowing technicians to isolate abnormal friction or wear in facility equipment.

Precision Localization: Utilizes beamforming algorithms to achieve ±1° localization accuracy, equating to an error margin of ≤1 cm at a 1-meter distance under 40kHz. This enables the clear differentiation of multiple, dense acoustic sources.

Operating Range: Effective detection distance spans from 0.3 meters up to 150 meters.
