    non-destructive testing >monitoring on-site vibrations

VMS-4000 is Thomas Instruments' answer to building site needs: it is an extremely compact vibration monitor, made up of a central unit with display, a triaxial geophone (nat.freq. 4.5Hz) and a microphone for measuring the shot in the air.

Thanks to the Seisware software supplied, you can get an immediate report with all useful information, for immediate interpretation.

A printer and external strobe light are also available as accessories.
