DEC5 Portable Readout Unit


DEC5 is a portable readout unit for vibrating wire instruments and thermistors, equipped with internal rechargeable battery, able to read almost all vibrating wire instruments on the international market.
The DEC5 is a very simple and intuitive readout unit to use, with immediate return of measured data on an alphanumeric display located on the front panel.
Great reliability, universality, ease of use and long autonomy, make DEC5 perfect for those who have to take manual measurements without the need to store data and without the need to programme automatic measurement cycles.
As an alternative to DEC 5, for larger storage requirements and automatic programming of measurement cycles, we offer our DEC3000 devices (see separate leaflet).


The DEC5 readout unit comes as a portable reading device for vibrating wire instruments and thermistors. The latest version has the ability to capture almost all vibrating wire instruments present on the national and international market.
Its great reliability, solidity, sturdy protective case and reasonable price, make the DEC5 an excellent device for those performing occasional test measurements during the various stages of processing or for working in particularly difficult conditions on sites such as:

  • Bridges
  • Dams
  • Tunnels
  • Piles
  • Railway lines
  • Monuments
  • Churches
  • Historical and cultural buildings
  • Various

Measurement Principles

The DEC5 internal electronics come from years of experience in the field of monitoring and more specifically the design and construction of monitoring instruments. The control unit provides the excitement of the sensor’s wire, measures the frequency of vibration and shows it on the alphanumeric display.
This product is definitely one of the most requested by operators who do not require particular functions from a control unit, but require high reliability, accuracy and speed in instrument readings, simplicity and the ability to read almost all vibrating wire instruments currently on the market.
