The CG-5 AUTOGRAV has a standard resolution of 1 microGal with 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.
Field repeatability tests are the best measure of a gravity meter’s performance. Documented field tests of the CG-5 AUTOGRAV meters show a standard deviation between individual readings and station values of better than 5 microGals.
The sensing element of the CG-5 AUTOGRAV is based on a fused quartz spring system. The gravitational force on the proof-mass is balanced by a spring, and an electrostatic restoring force. The inherent strength and excellent elastic properties of fused quartz, together with the limit stops around the proof-mass, permit the instrument to be operated without clamping. Additional protection is provided by a durable shock mount system.
Due to low mass and excellent elastic properties of fused quartz, tares are virtually unknown. Even after transport over rough roads and severe temperature shocks, the residual drift is minimal. The CG-5 AUTOGRAV can withstand a shock up to 20 G and the tare will be no more than 5 microGals.
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.
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.
The CG-5 AUTOGRAV is equipped with a radio-frequency remote start transmitter (keyfob) to allow measurement to be taken without disturbing the meter by touch.
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.
The Scintrex CG-5 maximizes your productivity delivering superior data repeatability in rough field terrain. Station positions are measured with the integrated GPS capability. Internal GPS and precise clock for X-Y positions and earth tide corrections.
