Key Features and Design Advantages
The thoughtful design of this digital Gaussmeter provides a suite of features that enhance its usability and performance in diverse environments.
Main Features:
- Compact Size and Enhanced Portability: With its small volume, light weight, and convenient handling, this Gaussmeter allows users to meet various measurement requirements with unparalleled flexibility. Its compact form factor makes it easy to transport between different sites, whether in a factory, a research lab, or an outdoor field setting. This ensures that precise magnetic field measurements are always within reach, regardless of the location.
- Extended Battery Life with Micro Power Consumption: Engineered with a sophisticated micro power consumption design, the device offers an impressive battery life of up to 50 hours of continuous use. This extended operational capability minimizes downtime and maximizes productivity, making it reliable for prolonged measurement tasks without the constant worry of power depletion.

A significant advantage is that the screen clearly indicates the polarity (North or South) of the magnetic pole being measured. This feature is invaluable for applications requiring precise magnetic orientation, such as magnet sorting, motor assembly, or magnetic material inspection.
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. Its extended battery life, clear display, and reliable accuracy underscore its value as an essential tool in any magnetic measurement toolkit.
