In-Depth Technical Specifications Explained
Understanding the technical specifications of a Gaussmeter is paramount for appreciating its capabilities and ensuring it meets the specific demands of your application. Here’s a detailed look at the core technical parameters of this advanced device:
Technical Specifications
- Supply voltage: 9 V battery: The device operates on a standard 9-volt battery, providing a readily available and easily replaceable power source. This ensures operational continuity even in remote locations where access to mains power might be limited, enhancing its portability and field utility.
- Display meter: 3 1/2 digital display: The 3 1/2 digit display provides clear and precise readings. This means the display can show three full digits (0-9) and a “half” digit, which can only be a 0 or 1. This configuration offers a good balance between readability and measurement range, allowing for accurate interpretation of magnetic field values.
- Measurement scope: 0 ~200mT, 0 ~2000mT (Accuracy 0~ 1200mT 1%, more than 1200mT 2% (Full range, check in uniform magnetic field)): This Gaussmeter offers two distinct measurement ranges: 0 to 200 milliTesla (mT) and 0 to 2000 mT. One Tesla (T) is equal to 10,000 Gauss (Gs), so 200mT equals 2000Gs, and 2000mT equals 20,000Gs. The dual range allows for precise measurement of both weaker and stronger magnetic fields. The stated accuracy of 1% for measurements up to 1200mT and 2% for measurements exceeding 1200mT indicates the reliability of the readings across its operational spectrum. “Full range, check in uniform magnetic field” suggests that the accuracy is verified under controlled conditions where the magnetic field is consistent, ensuring reliable performance in practical scenarios.
- Accuracy = 1%: This specification reiterates the high level of precision offered by the device. A 1% accuracy means that the measured value will be within 1% of the true magnetic field strength, which is crucial for sensitive applications requiring reliable data.
- Resolution: 0.1 mT (10Gs): The resolution of 0.1 mT (equivalent to 10 Gauss) signifies the smallest change in magnetic field strength that the device can detect and display. A high resolution like this is essential for applications where even slight variations in magnetic fields need to be identified, such as detecting minor defects in magnetic materials or fine-tuning magnetic systems.
- Weight: 450 gr: Weighing only 450 grams, the device is exceptionally lightweight. This characteristic significantly contributes to its portability, reducing user fatigue during extended periods of use and making it easy to carry in a tool bag or on a belt.
- Temperature error: – 0.06%/°; c: This specification indicates how the device’s accuracy might drift with changes in ambient temperature. A temperature error of -0.06% per degree Celsius means that for every 1°C increase in temperature, the measurement might slightly decrease by 0.06%. This relatively low error rate ensures consistent and reliable readings even when operating in environments with fluctuating temperatures.
- Frequency Range: 10Hz-200Hz: The operational frequency range of 10Hz to 200Hz specifies the spectrum of alternating magnetic fields (AC fields) that the Gaussmeter can accurately measure. This is particularly important for applications involving pulsed magnets, AC motors, or inductive heating systems, allowing for dynamic magnetic field analysis.
- External Dimensions: 150x70x30mm (LengthxWidthxHeight): These compact dimensions further emphasize the device’s commitment to portability. Its small footprint allows for easy storage and handling, making it suitable for tight spaces and field measurements.
- Working environment: Temperature: -10 °C ~ 40 °C, humidity: 35 ~ 75%: This defines the optimal environmental conditions for the device’s operation. It ensures that the Gaussmeter performs reliably within a broad temperature range, from moderately cold to warm conditions, and across a typical range of humidity levels. Operating within these parameters is vital for maintaining the device’s accuracy and longevity.
Conclusion: The Versatility of a Professional Gaussmeter
In conclusion, this handheld digital Gaussmeter stands out as a robust and highly versatile instrument for professionals requiring accurate and consistent magnetic field measurements. Its intuitive design, coupled with its comprehensive technical specifications, makes it an ideal solution for a wide array of industrial, research, and quality control applications. From ensuring the integrity of magnetic components to optimizing the performance of electrical systems and adhering to safety standards, this Gaussmeter provides the precision, portability, and reliability necessary for critical magnetic field analysis.

An Industrial Gaussmeter (Magnetometer) is a high-precision electronic measurement instrument equipped with a sensitive Hall-Effect probe. It accurately measures the surface magnetic field strength (Flux Density) and residual magnetism of materials, displaying values in Gauss (G) or Tesla (T) for strict factory quality assurance.
They are mandatory in QA/QC laboratories, for food/pharma safety auditors (HACCP/BRC) checking the strength of magnetic separators, in automotive OEM plants verifying sensor/motor magnets, and in heavy machine shops measuring residual magnetism on steel blocks after CNC grinding.
Global food safety standards (like BRC, IFS) mandate that magnetic separators used in production lines must maintain a specific minimum strength (e.g., 10,000 Gauss) to effectively catch metal. A calibrated Gaussmeter allows QA engineers to perform documented, daily/monthly audits to prove the magnets have not degraded.
Yes, this is a critical industrial function. After CNC grinding or magnetic lifting, steel parts retain a weak magnetic field that attracts destructive metal swarf. High-resolution Gaussmeters can measure extremely low fields (e.g., 0.1 to 10 Gauss), allowing QA to verify that Demagnetization processes were successful before final assembly.
Our professional B2B instruments offer wide measurement ranges, typically from 0.1 Gauss (for residual fields) up to 30,000 Gauss (3 Tesla) for extreme Rare-Earth NdFeB magnets. They feature high accuracy (e.g., ±1% or ±2%) with auto-ranging, Peak Hold functions, and polarity (N/S) indicators.
The Hall-Effect sensors are delicate, but our industrial probes are housed in rigid brass or flexible protective sheaths. We supply both Transverse probes (for measuring flat surfaces and narrow gaps in motors) and Axial probes (for measuring inside magnetic cylinders and coils), engineered for factory floor use.
Absolutely. For strict corporate compliance (ISO 9001, IATF 16949, HACCP), our Gaussmeters are supplied with official, traceable Laboratory Calibration Certificates. We also offer advanced models with USB/Bluetooth data logging software to export measurement reports directly to your factory's QA database.
