Key Features
Dual Measurement Modes
Non-Contact (Optical): Uses a laser beam and reflective tape to measure RPM from a distance—safe and ideal for rotating or inaccessible parts.
Contact: Uses mechanical adapters (wheel/cone) for direct RPM or surface speed readings.
Wide Measurement Range
Accurately measures RPM from 2 to 99,999 RPM (non-contact) and 0.5 to 20,000 RPM (contact) depending on model.
High Accuracy & Fast Response
Provides stable readings with ±0.05% accuracy, ideal for precision diagnostics.
Large LCD Display with Backlight
Bright, easy-to-read screen shows current RPM and additional functions.
Data Hold & Max/Min Function
Freeze the current reading and track peak RPM during testing.
Auto Power Off
Conserves battery life during field operations.
Rugged & Portable
Ergonomic handheld design with shock-resistant casing suitable for harsh environments.
