- Mechanical fault detection for early identification of bearing problems, preventing costly downtime
- Quantify leak rate and cost of industrial gas and compressed air leaks, to prioritize repair and calculate savings
- On-camera and in-software severity assessment and type classification of partial discharge (PD) issues
- Automatic frequency tuning, 8x zoom, 12 MP digital camera, GPS data integration, IP54 rating, and a QR code reader
- Fleet management functionality for efficient tool usage and maintenance across large-scale operations
- Detect, locate, classify and assess partial discharge faults, compressed air and gas, and identify bearing issues efficiently
- Intuitive, light weight, one handed operation requiring minimal training
- On-device partial discharge type and severity analysis with recommended actions
- On camera measurement and cost analysis for compressed air and common industrial gases including ammonia, hydrogen, CO2, methane, helium and argon
- Bearing assessment
