// CLEARER IMAGE Low natural frequency : 5Hz BETTER PERFORMANCE Higher sensitivity compared to conventional geophone : 80V/m/s SG-5 is a new geophone featuring a high-sensitivity and a low natural frequency. This new sensor offers comparable output sensitivity to an array of geophones while providing lower frequency recording capabilities down to 5Hz. Especially designed for single sensor application, SG-5 is particularly adapted for microseismic operations in combination with UNITE but also fully compatible with existing Sercel 428XL cable system. Specifications subject to change without...

HIGH PERFORMANCE GEOPHONE SENSOR // CLEARER IMAGE Very Low distortion: < 0.075% // HIGHEST RELIABILITY Demanding Validation Process // EXTREME WORKING CONDITIONS Operating Temperature: -40°C / +70°C The SG-10 was developed utilizing rare-earth magnet technology to achieve very low distortion and the highest tilt tolerance in the industry. This technology, coupled with a specific magnetic geometry, results in one of the most advanced geophones in the seismic industry. Low Distortion Typical distortion vs. tilt angle SG-10 and conventional geophone 0.25 Natural frequency Distortion Intrinsic...

// CUSTOMIZED SOLUTIONS Bespoke manufacturing // HIGHEST RELIABILITY Demanding Validation Process // EXTREME WORKING CONDITIONS Operating Temperature: -40°C / +70°C The JF-20DX Geophone is well-suited for a variety of applications including oil exploration, mining, engineering and scientific research. Available in two different cases, land or marsh, the JF-20DX also has a selection of optional frequencies: 10 Hz, 14 Hz, 28 Hz and 40 Hz. Recognized for its high level of reliability, this geophone is capable of increasing the productivity and efficiency of seismic crews. The JF-20DX is built...

// EXTREME WORKING CONDITIONS Temperature range up to 205°C // HIGH PERFORMANCE High sensitivity geophone : 52.0 V/m/s // HIGH RELIABILITY Strict validation process : 500h@205°C Its high sensitivity specifications make it also well adapted to microseismic and hydraulic fracturing monitoring surveys. Note: Sercel reserves the right to change its specifications without prior notice. All specifications are typical at 20°C
