DX-65 High-Precision 3-Axis Portable Gaussmeter

The DX-65 utilizes the latest magnetic field measurement technology. It features a 5-inch capacitive touch screen (720x1280 resolution) with intelligent backlight adjustment and a fully tactile operation interface. It integrates a bilingual (Chinese/English) interactive system, enabling real-time display of 3-axis magnetic field measurements, temperature, angle, maximum value, minimum value, date, battery level, time, and other parameters.

 

1. High-Precision Measurement: Supports 3-axis magnetic field measurement with excellent orthogonal angle correction technology (better than 0.1°).

2. Intelligent Operation: 5-inch capacitive touch screen, supports Chinese/English language switching, intelligent backlight adjustment.

3. Multifunctional Data Acquisition:

• Supports peak acquisition (RS, BRB), FFT spectrum analysis, and graphical curve plotting.
• Supports vector summation, automatic/manual range switching.
• Data can be controlled and interacted with via command sets over the USB interface.

4. Probe Compatibility: Optional probes include the world's smallest package size (0.25mm) and high/low-temperature (-269°C to 200°C) 1D, 2D, and 3D probes.

5. High-Speed Acquisition: Supports variable speed acquisition from 0–300 samples/second with excellent measurement repeatability.

6. Calibration Certification: Complies with JF1832-2020 (1mT–2.5T) Gaussmeter calibration specification and JF2151-2024 Medical Magnetic Resonance Imaging System calibration specification.
