- Acceleration, Velocity measurement, RMS measurement value.
- Metric & Imperial display unit.
- Frequency range 10 Hz - 1 kHz, sensitivity relative meet ISO 2954.
- Microcomputer circuit, intelligent function, high accuracy.
- LCD display, easy read out.
- Complete set with the Test pin and the Magnetic base are the standard accessories.
- Built-in low battery indicator.
- Heavy duty & compact housing case.
- IP65 protection.
- Compact size, light weight.
- Soft carrying case is the optional accessory
