The Z400 gravity meter is an instrument that measures the relative change of gravitational acceleration value. The instrument's sensor is made of quartz. It adopts zero reading and is equipped with a precise temperature compensation device.
The Z400 gravity meter can be widely used for gravity prospecting in the field of geologic structure and minerals (including gravity general surveys, gravity detailed surveys and regional gravity surveys).
