Visual sound localization
Sound-map overlays identify source regions and help move from broad scanning to targeted review.
WHY ACOUSTIC IMAGING
See where leaks and abnormal discharge originate
Background-noise filtering
Adjust frequency band, threshold and dynamic range to focus on target signals in complex environments.
Maintenance prioritization
Combine leak analysis, equipment location and operating records to prioritize findings for maintenance.
Documented inspection findings
Save sound maps, photos, video and annotations for maintenance handover and before-and-after review.

VIEW PRODUCT →CORE CAPABILITIES
From sound localization to inspection records
MEMS array imaging
Multichannel microphones and imaging algorithms display source distributions over the visible scene.
Gas-leak localization
Inspect compressed-air systems, valves, flanges and connections; detectability depends on pressure, distance and surroundings.
Partial-discharge analysis
Acoustic localization and PRPD information help screen abnormal emissions around insulation for further review.
Thermal inspection
VS138XH and VS130EP add 640 × 512 thermal imaging for surface-temperature distributions and anomalies.
Distance and target confirmation
VS138X / VS138XH include laser ranging; record distance by suitable means on other models for repeat inspections.
Review and reporting
Recording, playback and annotations preserve findings; select report functions according to model configuration.
ACOUSTIC AND THERMAL INSPECTION
Inspect sound sources alongside thermal anomalies
An acoustic array overlays source locations on the visible scene, while thermal imaging shows surface-temperature distribution. VS138XH and VS130EP provide both types of information for reviewing suspected leaks, discharge or overheating. VS138X and VS128N support surveys focused on acoustic localization. Interpret findings alongside target distance, operating state and background noise.
COMPARE CONFIGURATIONS
APPLICATIONS
Applications across leaks, discharge and mechanical noise
Compressed-air systemsInspect fittings, hoses and air-use points, then recheck repaired locations under comparable operating conditions.
Electrical equipment surveysScreen switchgear, insulators and connections, then review discharge patterns alongside equipment condition.
Petrochemical and process plantsLocate leak emissions around valves, flanges and process pipes, documenting the medium, pressure and inspection conditions.
Mechanical noiseScan abnormal noise regions on operating machinery, adjust analysis bands and record locations for further diagnosis.
Rail and transport equipmentInspect pneumatic systems, connections and equipment noise at defined locations for repeat surveys.
Combined acoustic and thermal reviewUse thermal-equipped models to record sound sources and temperature distributions for complementary review.SELECTION PROCESS
Six steps to define the inspection configuration
Define the target
Identify gas leakage, electrical discharge or mechanical noise and the records required.
Confirm distance and environment
Record distance, access, background noise and reflective surfaces to assess the inspection setup.
Match frequency and analysis
Choose a frequency range for the target spectrum and confirm leak, PRPD or transient-analysis needs.
Choose display and thermal options
Choose a 5- or 10-inch platform and confirm thermal-imaging and focusing-distance requirements.
Check power and data
Confirm survey duration, batteries, storage, annotations, connectivity and reporting workflow.
Validate in the field
Validate localization, operation and record quality on representative targets before confirming the configuration.

GAREXON
Configure the equipment around the inspection task
Start with the target
Define the configuration around the medium, equipment and access conditions rather than isolated figures.
Verify each configuration
Check acoustic, thermal, laser and data functions against the documentation for the specific model.
Validate representative conditions
Use targets that represent real distances, noise and pressure to assess suitability.
Consistent recording
Record location, operating conditions and settings so repeat inspections can be compared.
Match accessories and documents
Confirm power, storage, support accessories and documentation for the planned surveys.
Support follow-up review
Organize locations, sound maps and thermal images into clear records for maintenance and technical review.
