State-of-the-Art Software Features
Field-upgradable software modules designed for advanced asset integrity evaluation and boiler tube inspection.
Live A-Scan & B-Scan Display
Display live RF or rectified A-scan waveforms for acoustic echo verification alongside cross-sectional B-scan profiles for corrosion mapping.
Internal Oxide Scale Mode (OS)
Simultaneously measures and displays boiler tube steel wall thickness and internal oxide scale thickness at their respective acoustic velocities to extend boiler tube life.
True Thickness Under Coating
Echo-to-Echo measurement displays substrate thickness and paint/coating thickness simultaneously without stripping anti-corrosion paint.
IP67 Waterproof & Rugged Housing
Custom-molded IP67 dustproof and waterproof enclosure with ergonomic rubber boot designed for harsh offshore platforms and industrial rain.
Fast 25Hz Scan Rate & Alarms
Rapid 25 Hz Min/Max capture mode with haptic vibration alarms (ideal for noisy plant environments), audible beeps, and screen color changes.
Data Logging & Microsoft Excel Sync
Stores unlimited readings on up to 32GB Micro SD memory cards and exports directly to Microsoft Excel via DataXLS software.
