HA3A Acoustic Camera | Gas & Vacuum Leak Detector

HA3A Gas Leak Acoustic Camera

The Hertzinno HA3A, released in 2026, is a dedicated acoustic imaging camera for gas leakage and mechanical noise detection. Equipped with 128 digital MEMS microphones and operating across a 2kHz to 100kHz bandwidth, it provides industrial-grade sensitivity in a highly accessible package. The device features built-in vacuum leak detection and a laser rangefinder, making it the standard tool for facility operations and maintenance teams.

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.
