Digi-Shock Meter

The Digi-Vibro Model-1332A is a high-accurate Digital Vibration Meter with a light weight and small pocket size. The Model-1332A offers extremely simple operation, eliminating troublesome range attenuator changing. Adding to the easy operation, applications of it may be extended to to various fields with wide range of 10 to 5,000 Hz.,
Features:
  • Extremely small size and light weight offers complete portability in field use.
  • A charge amplifier Input is incorporated to enable far-point vibration measurements, eliminating influences originated in length of input cable.
  • No range selection is needed for acceleration measurement up to 200m/s2, for velocity measurement up to 200mm/s(RMS) and for displacement measurement up to 2 mm p-p.
  • A hold-function is provided for digital readout holding which insures easy reading.
  • A commercially-available transistor-use dry battery is used as the power source for complete portability. And the battery alarm system is incorporated for battery check.
  • Piezo Electric Pickup is used as the input transducer for long life operation and wide frequency range of 10 to 5.000 Hz.
  • Full accessories of a contact pin, a handler and a magnetic holder are provided as standard for various field use.
