Overview

The SMT-200 is the latest addition to the Sensor range of geophone testing equipment. Due to the
advanced technology used in the design it has all the features of previous generation testing
equipment in a smaller and more compact unit. Its easy to use menu system allows the SMT-200 to be
quickly configured to test virtually any type of geophone string. Internal automatic calibration
eliminates the need for regular maintenance.
The Docking station is provided to manage battery charging and communication between the
SMT-200 and the PC.
The SMT-200 can be operated from lead-acid gel batteries (2 supplied) or connected to the docking
station for file transfer. The battery pack will supply enough power for 4 hours heavy field use.
