The FOTRIC H-series high-performance acoustic imaging cameras set a new standard in industrial inspections. The series, which includes the H4 and H6 models, is now expanded with the advanced FOTRIC H6+ and the top-of-the-line FOTRIC H7. Combining exceptional sensitivity, advanced leak detection, and partial discharge diagnostics, the H-series enables professionals to identify even the faintest gas leaks or electrical discharges—preventing costly failures and ensuring equipment reliability in the most demanding environments.

The FOTRIC H-series boasts exceptional sensitivity thanks to its array of up to 345 MEMS (Micro-Electro-Mechanical Systems) digital microphones on the H7 model. This advanced technology ensures the camera detects even the faintest acoustic signals, identifying small gas leaks or minor electrical discharges that could otherwise go unnoticed until they escalate into major issues.
Precision Targeting for Enhanced Diagnostics
A standout feature of the FOTRIC H-series is its Acoustic Focus Mode. This mode filters out background noise and interference, allowing the camera to zero in on a specific area of interest.
With this precision targeting, inspectors can accurately pinpoint the source of issues—whether it's a subtle gas leak or a localized partial discharge—without being distracted by surrounding noise.
Digitized Workflow and Automated Analysis

The advanced H-series models (H6+ and H7) revolutionize inspections. Both models feature AI Diagnosis for Partial Discharges, which automatically identifies surface, floating, and corona discharges and assesses their severity. They also support On-Device Reporting to generate professional Word or PDF files. The H7 model further enhances this workflow with the exclusive NaviPdM® Venus acoustic data management system for a fully digitized process.
Leak Evaluation and Partial Discharge Detection

The FOTRIC H-series excels in its dual capability to evaluate gas leaks and detect partial discharges. By calculating the cost of leaks, users can prioritize repairs based on potential savings. At the same time, the automated partial discharge diagnosis identifies the type and severity of electrical discharges, making it an essential tool for managing assets efficiently, reducing downtime, and preventing costly failures.
The H-series Leak Evaluation mode does more than just detect leaks—it quantifies their financial impact on compressed air systems, gas pipelines, and other pressurized systems. By calculating the cost of leaks, users can prioritize repairs based on potential savings, making maintenance decisions more strategic and impactful.
The H-series takes Partial Discharge (PD) detection to the next level thanks to automated diagnosis, accurately identifying the type of discharge occurring. This feature is vital for electrical systems like transformers and switchgear, where different types of discharges signal varying levels of risk.
