SENSEBOX BROADBAND

BROADBAND PORTABLE SEISMIC SENSOR

SENSEBOX-BROAD-P Series seismometers provide a very smooth and low noise

measurement quality at a very broad frequency spectrum with force balancing and

force feedback characteristics.

This model which is particularly developed for portable purposes, could also be

preferred in permanent stations since it provides a measurement sensitivity beyond

mobile use. This Sensor has a very robust structure and does not require any extra tool

or procedure at transportation/ mounting stages.
