SMT 200 & SMT 300

This fourth generation of the SMT-series geophone tester is equally at home in the laboratory or field environment. The SMT-300 sets the industry standard for testing geophone strings or individual elements to manufacturer's standards.

An internal NiMH battery will power the SMT-300 for over 20 hours of continuous operation, while the versatile onboard charger can accommodate 12 - 30 VDC (110 - 230 VAC adaptor provided). When the fast-charge mode is selected, your SMT-300 can be recharged and ready to use in as little as 2 hours.
