DX-61 High-Precision One-Dimensional Portable Gauss Meter

 

The company has developed Hall sensors with ultra-small size, wide temperature range, high linearity and large measurement range. The linearity is up to 0.01% and the active area size can be as small as 0.028mm. The device is equipped with a patented technology for orthogonal angle correction of the built-in probe, with the orthogonal deviation controlled within 0.1°. The whole machine adopts a professionally optimized hardware circuit, including an ARM Cortex high-performance 32-bit microprocessor and ULLASS ultra-low loss sampling patent technology, achieving high-speed response, low latency and high signal-to-noise ratio for weak signal acquisition. The high-definition capacitive touch screen provides fine data display and wide viewing angle, and the humanized interaction design makes the operation smooth and convenient. The product complies with international certification standards such as ISO9001, CE and IQNET. The probe calibration strictly follows the JF1832-2020 (1mT~2.5T) magnetic flux density meter calibration specification.
