Hazardous Location Acoustic Imaging Camera for Gas Leak, Mechanical Fault, and Partial Discharge Detection
The Si2x-Pro Acoustic Imaging Camera is specifically designed for use in hazardous gas and explosive dust environments, to easily reduce leaks of toxic or flammable gases to improve safety, or cut expenses associated with compressed air or gas leaks in your facilities. With its advanced analysis tools, the Si2x-Pro provides a robust solution for lowering costs associated with mechanical bearing issues and partial discharge on electrical equipment. Engineered for hazardous operations, it offers best-in-class performance, decision support, and fleet management, along with enterprise data integration for optimal efficiency and safety.
For those not requiring partial discharge detection, you can opt for the Si2x-LD for leak and mechanical fault detection.

Advanced Leak and Partial Discharge Detection
Precisely detect, locate, and measure compressed air leaks, gas leaks, and partial discharges. Identify and quantify both minor and elusive issues from up to 200 m (656 ft) away—boosting operational efficiency and ensuring safety.

Mechanical Fault Analysis
Save on costly repairs, reduce downtime, and enhance maintenance efficiency by identifying bearing and other mechanical defects before they overheat or cause equipment failure.

Fleet Management Functionality
Ensure optimal use and maintenance of equipment in large-scale industrial settings with fleet management, cloud data integration, and OTA software updates. Combine acoustic and thermal imaging in the same report.
