Description
The FOTRIC H4 is a professional-grade acoustic imaging camera built for serious industrial inspection. Equipped with 112 MEMS digital microphones and a full partial discharge detection suite, it diagnoses both leak faults and electrical PD faults in a single device.
The H4’s Acoustic Focus Mode filters background noise to deliver precise signal isolation — essential in noisy plant environments. Automatic partial discharge classification (surface, floating, corona) provides instant, actionable fault diagnosis without post-processing.
