The FOTRIC H4 Acoustic Imaging Camera is a high-performance device designed for precise air and gas leak evaluation and partial discharge detection. It features 112 MEMS digital microphones, providing exceptional sensitivity to detect even the faintest acoustic signals. The camera operates in two primary modes: LQ Mode, which displays the leakage level, and PD Mode, which presents a PRPD diagram adapted to different AC frequencies (50/60Hz). Its Acoustic Focus Mode filters out background noise, ensuring precise targeting and accurate diagnostics. The FOTRIC H4 is equipped with a 5-inch, 1280x720 pixel LCD touchscreen display with Gorilla Anti-Explosion glass. With a compact and lightweight design, weighing approximately 2.86 pounds (1.3 kg), and an IP54 enclosure rating, it is both portable and durable, suitable for various industrial environments. The device also supports on-device analysis and comes with AnalyzIR professional thermal and acoustic image analysis software for comprehensive post-inspection evaluation.
