Key Capabilities & Measurement Modes
Everything needed for plant predictive maintenance in a compact 380g hand unit.
ISO 10816-3 Severity
Instantly measures overall RMS velocity (10 - 1000 Hz) and evaluates machine health status against official ISO 10816-3 severity charts.
FASIT Automatic Diagnosis
Adash's patented expert algorithm automatically detects unbalance, misalignment, mechanical looseness, and bearing damage directly on screen.
Vibration Stethoscope
Audible headphones listening output allows maintenance technicians to physically hear bearing noise, cavitation, and gear mesh friction.
FFT Spectrum & Envelope
800-line FFT frequency spectrum and Demodulation Envelope analysis for early detection of roller bearing impacts and gear defects.
Free DDS Software Route
4 MB memory stores over 120,000 overall values. Connects via USB-C to free Adash DDS software for route planning and trend analysis.
LED Strobo & IR Temp
Built-in LED stroboscope for speed measurement (0.17-300 Hz) and non-contact IR temperature sensor (-70°C to +380°C).
