Digital gaussmeter DX-630

hand-heldportableUSB

Introduction
Dexinmag has developed an ultra-small Hall sensor with an ultra-wide operating temperature range, high linearity (max 0.01%) and high sensitivity (active area 0.028 mm). The device integrates a patented 3D probe orthogonal angle correction (orthogonality deviation ≤ 0.1°). The host incorporates professionally designed analog and digital circuitry (ARM Cortex 32-bit MCU) and patented ultra-low-loss sampling (ULLASS) for high-quality weak-signal acquisition. The instrument features a high-definition large display with wide viewing angle and a capacitive touch user interface. The product complies with ISO9001, CE and IQNET certifications.

Interface and Functions
Measurement interface displays 3D magnetic field value, vector magnetic field, deflection/tilt angles, range, AC/DC mode, field direction, units, time, probe ID and battery level. Touch controls include zeroing, AC/DC switch, unit switch, range switch, data save, max/min display, screen hold and menu. Menu settings: threshold settings, version info, curve viewing, communication settings, device settings, calibration, and save/view. Curve functions: time-domain plotting, peak detection and FFT spectrum display. Device settings: time, backlight mode/brightness, buzzer on/off, language and selectable filtering methods (average, sliding, none). Host software supports recording/plotting, automatic probe calibration/host auto memory, automatic zero/range, threshold alarm and selectable display units (e.g., milligauss, nanotesla).
