The FG5-L series absolute gravimeter is a simplified version of the FG5 absolute gravimeter optimized for small size, speed of data acquisition, ease of use, portability and price.
Many of the subcomponents of the FG5-L are compatible with the FG5 in order to allow an upgrade path to the FG5.
This gravimeter offers an attractive trade-off between low price and precision in an instrument that is easy to use in the field.
