CG-6 AutoGrav
from Scintrex
The new CG-6 is the latest generation micro gravity meter from Scintrex ltd. Utilising the same patented quartz sensor technology as its predecessor (the CG-5) the CG-6 offers fast, reliable and precise gravity measurements. Designed with the end user in mind the CG-6 interface is intuitive and simple to operate. With 4GB internal flash memory and the option to transfer data in real time to a recording tablet data is constantly backed up.
The all new Lynx LG application provides additional in-field data quality control and analyses at the operator’s finger tips. With real time tide, tilt and ocean load corrections being displayed on screen during data acquisition it is possible to isolate sources of noise and rectify them quickly.
Features:
- Integral GPS (I.e. not an add-on stuck out the side)
- Bluetooth and USB connectivity for easier and faster data download
- Choice of Berger, ETSTAB or user defined tide corrections
- In-field simple Gravity profiles and Bouguer anomaly maps
- Lynx LX software, for mapping real-time positioning, previous survey/station recall, station /route import capability and post processing,
- Simplified tilt and drift calibration interface via Lynx software
- User selectable filters – Blackman-Harris (FIR) or moving average
- Data acquisition software permits user to upload predefined station coordinates for improved survey management
- Addition of Ocean Load Correction – choice of Schwiderski (default), FES2004 or CSR3.0.
- Graphical display of instrument metadata for improved data QC. Including; level, tide, load, temperature, drift. Toggled view between raw measurement values and gravity correction in μGal.
- More intuitive user interface, faster levelling
- Can operate via rugged tablet PC
- Greater data storage
- 35% lighter
- Reduced profile means better performance in windy conditions

Shipping Notes:
All CG-6 transit cases will be strapped to a standard sized pallet for shipping. This helps to ensure the instrument is handled correctly during shipping.
It is common for the CG-6 batteries to fully deplete when shipped overseas via courier, to avoid this we recommend hand carrying the equipment on a commercial flight. Geomatrix will support any costumer who wishes to transport a CG-6 in this manner by delivering the instrument to Luton Airport.
