CG-5 Autograv Gravity Meter

The CG-5 Autograv is a microgravity meter with a standard resolution of 1 microGal and a standard deviation that is < 5 microGals. It is the fastest, lightest, most cost efficient gravity meter on the market today. With minimal training a user can quickly collect and record reliable gravity data.

Fully Portable

The CG-5 AUTOGRAV incorporates the gravity sensor, control keypad, electronics, and batteries into one lightweight weather resistant instrument case. No cables to trip over, no handheld devices, just an easy to use and carry, self-contained gravity meter. GPS Station Referencing Internal GPS Receiver enables GPS station referencing from a 12 channel smart GPS antenna connected via the RS-232 port. Standard accuracy: <15m; DGPS (WAAS): <3m.

Touch Free Operation

This instrument is equipped with a radio-frequency remote start transmitter (keyfob) to allow measurement to be taken without disturbing the meter by touch.

Automatic Compensation and Correction

By using the electronic tilt sensors, the CG-5 AUTOGRAV is constantly updating information from the internal tilt sensors. The CG-5 AUTOGRAV can automatically compensate measurements for the errors in instrument tilt. This operator selectable feature ensures that when measurements are taken on unstable ground, errors due to instrument movement are automatically eliminated. Based on operator entered geographical location and time zone data or GPS information, the CG-5 AUTOGRAV can automatically calculate and apply a real time tidal correction to each reading.
