Complete set
Professional kit in hard case, everything has its place and is well protected.
Interchangeable Battery System
Includes 3 interchangeable Li-ion batteries and a dual bay charger to provide you with up to 10 hours of operation (AI56, 6 hours for the AI76). You can stay powered up for even the longest inspections.
Low-Noise mics and adjustable bandwidth
With Low-noise MEMS microphones and an adjustable bandwidth range from 0 kHz to 96 kHz. The HIKMICRO AI series provides an easy and effective way to instantly locate gas leak detection and partial discharge from high-voltage systems.
Real-time estimates of leakage data
The HIKMICRO AI series offers real-time estimated leak rate, leak cost for gas leak detection. AI series can filter noise to “visualize” sound with a large 4.3" LCD touch screen even in noisy environments.
Smart Partial Discharge Detection (n/a for AI56L)
When placed in Partial Discharge mode, the AI series identifies corona, floating, surface, or particle discharge on high voltage systems that can lead to equipment failure. This is instantly displayed onscreen and can be saved for documentation and reporting.
Analyzer Acoustic
Analyzer Acoustic for PC is included at no additional cost or recurring fees. Simply import images from the camera to quantify issues, analyze field images, highlight concerns, and create reports for repairs, field audits, or energy rebate programs.
Voice & Text Annotations
In addition to supporting voice, text annotations to the image helps to improve inspection efficiency and productivity.

Presentation of the HIKMICRO AI series devices for rapid detection of gas leaks and partial discharges in industrial and electrical installations. The basics of sound and sound pressure are explained, typical areas of application (including manufacturing, oil & gas, energy suppliers) are highlighted, and the most important technical features of the AI56 and AI76 models are described. The advantages over classic leak detection and ultrasonic testing devices, including software support for analysis and reporting, are also explained.
