Ultra-High Sensitivity and Accuracy: Industry-leading "" technology and a built-in self-degaussing circuit inherent zero-point errors, resulting in exceptionally high initial accuracy and eliminating the need for manual calibration. Ultra-High Resolution: Up to 22-bit effective resolution and noise as low as 0.06 mGauss enable detection of extremely weak magnetic field changes, even those generated by currents. Wide Measurement Range: A wide dynamic range of ±30 Gauss allows detection of both weak signals from the Earth's magnetic field (-0.5 Gauss) and stronger interfering fields without saturation. Excellent Temperature Stability: A built-in temperature-compensated sensor automatically compensates for temperature drift, providing stable and reliable measurement data across the full temperature range (-40°C to +85°C). Ultra-Low Power: Optimized for battery-powered devices, consuming only 4μA in single-shot measurement mode, it's ideal for always-on portable devices.
