The FOTRIC acoustic and optical instrument has two main detection modes: leakage mode and partial discharge mode. It can effectively detect on-site issues like leaks, partial discharges, vibrations, and unusual noises. With various smart diagnostic features, it significantly boosts user detection efficiency, ensuring fast and accurate fault diagnosis and maintenance.


2 Professional Inspections, 1 Device
(1) Gas Leak Detection
Directly locates leak points; detects even tiny leaks; evaluates leak rate and economic loss, providing data support for decision-making.
(2) Partial Discharge (PD) Detection
PD locations clearly visible; detectable at ultra-long distances; intelligent diagnosis of PD types: floating discharge, corona discharge, surface discharge.

Full Range of Practical Features, Ultimate User Experience

FOTRIC acoustic imager features two main inspection modes — leak mode and PD mode — effectively detecting leaks, PD, vibration, abnormal noise, and other on-site issues; equipped with multiple intelligent diagnosis functions, significantly improving inspection efficiency and ensuring fast, accurate fault diagnosis and maintenance.
Gas Leak — Leak Assessment Function
Gas leaks are a common challenge in factories, including compressed gas, flammable gas, toxic gas, and more. These leaks may lead to energy waste, equipment failure, fire risk, health hazards, and environmental impact.
FOTRIC acoustic imager, with its efficient, intuitive, and accurate features, helps users promptly discover leak sources and supports evaluation of leak rate, leak level, and economic loss, providing data support for scientific factory decision-making and reducing the risk of further losses.

Partial Discharge — Intelligent Diagnosis of PD Types
FOTRIC acoustic imager identifies and locates PD sources by detecting acoustic signals generated by partial discharge from high-voltage equipment, power cables, insulators, and other equipment, helping maintenance personnel promptly discover and handle potential electrical faults, ensuring normal and safe operation of power equipment.
On-site, FOTRIC acoustic imager intelligently diagnoses PD types: floating discharge, corona discharge, surface discharge, helping inspection personnel efficiently analyze faults.

Acoustic Image Delay Function
FOTRIC acoustic imager records fleeting sound sources using a delay function, helping detect intermittent leaks, PD, vibration, abnormal noise, and other on-site issues — never missing a single fault.

Acoustic Image Focusing Function
In noisy acoustic environments, FOTRIC acoustic imager supports focusing on key sound source locations, shielding surrounding noise interference, greatly improving inspection accuracy.

Professional Analysis Software
Import acoustic images into professional analysis software, supporting multi-dimensional analysis and fast batch auto-generation of professional reports.
