Ground magnitometer GT-MVS

'Walking' magnetometer GT-MVS

Purpose

Magnetometer GT-MVS is used for measuring the Earth's magnetic field during ground-based surveys.

Its outstanding sample rate (up to 500 Hz) allows high precision magnetics even in areas with high level of industrial noise.

GT-MVS provides the ability to record data automatically or by an operator's command at the control points (pickets). To control device work, to record data at the pickets, to monitor data in real time, to review the recorded data PDA is used, which is connected to the magnetometer through a standard wireless network connection (Wi-Fi).

And to transfer the data through the Internet GT-MVS has GSM-modem.
