Sensor introduced the first geophone testing equipment in the mid 1980's and has been setting the industry standard ever since. Even our competitors use Sensor test equipment in their geophone production and testing facilities.
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.
The water resistant, rugged aluminum body of the tester, improved durability keypad, and provided custom carrying case ensures that your SMT-300 will provide all the reliably and performance that you demand for years to come.
SHARP Hydrophone Tester
Testing hydrophones in the field can be complicated with results strongly influenced by the level of the measurement drive signals.
The Sensor Hydrophone Acoustic Response and Polarity (SHARP) tester allows a quick, accurate, and reliable in-field acoustic measurement of hydrophone sensitivity and polarity.
GRIP String Analyzer
The GRIP Geophone String Analyzer is a hand-held unit, allowing a quick and efficient method of checking Geophone string Resistance, Impedance, and Polarity (GRIP). It is calibrated for the string parameters by a plug-in module and any deviation from the nominal values are displayed on a panel meter.
