The Model “G” Gravimeter is able to collect the highest accuracy of gravity readings obtainable due to the patented Zero Length Springdesign. The repeatability of the meter is 0.1 milligal and accuracy is better than .04 milligal. The instrument is used for measuring variation in gravitational attraction.
These are just some of the application we have performed surveys on with gravity meters:
Determining Basement Structures
Locating Hard Minerals
Salt Domes
Reefs
Faults and Fractures
Locating geological features with density changes such as igneous intrusives
Defining boundaries of sediment and igneous material
