DX-330 Digital Vector Magnetometer


DX-330 Digital Vector Magnetometer uses the latest technology for magnetic field measurements, being the world’s leading level. The panel operation is very easy, has good man-machine communication interface. VGA display screen with large size, it can easily display all the information you need, and you can make the choice of whether to display. All selection can be realized by the operation button on the front panel. VGA monitor can simultaneously display a variety of different measurements in each channel: three dimensional magnetic field density, temperature, maximum, minimum, date, time. DX-330 Digital Vector Magnetometer has function of data storage, real-time data digital output and analog signal output of each channel. It can be matched with triaxial fluxgate probe.
