Micro-g LaCoste is proud to introduce the gPhoneXgravity meter as the latest member of its land gravitymeters. The gPhoneX gravity meter is based upon theLaCoste and Romberg technology that has dominated landgravity meters since 1939.The gPhonex gravity meter has a low drift so that it can be used tointegrate periodic singals (like earth tides) for very long time periods (years).The gPhoneX also has excellent hight frequency response so they can be usedto monitor higher frequency non-periodic events such as earthquakes. ThegPhoneX can be coarse-ranged over 7000 milliGals (worldwide, and has a100 milliGal dynamic range during measurement.The versatile gPhoneX gravity meter has a sophisticated data acquisitionsystem synchronized by a rubidium clock that can be locked to GPS so thatarrays of gPhoneXs can be used to give a wider area picture of seismic or longperiod gravity changes due to subsurface density changes. The instrumentcan be monitored and controlled via the internet for remote operation.The principal behind the Micro-g LaCoste’s gPhoneX is the patented L&Rzero-length spring suspension system. The gPhoneX is based upon theG-Meter, but with significant upgrades:• It has an improved thermal system, a double-oven, for moreprecise temperature stability.• It has a true vacuum seal so that it is completely insensitive tobuoyancy changes due to atmospheric changes• It employs the Aliod beam nulling system for precise digitalmeasurement of gravity with 0.1 µGal resolution.The complete Micro-g LaCoste gPhoneX System is a light weight, compactsystem and ships with three major components at a total weight includingcarrying case of 58 kg.www.microglacoste.com
