Gauss Meter/Tesla Meter and Reference Magnet Calibration at FARE Labs
Magnetic fields play a significant role in modern industries, scientific research, and technological development. Accurate measurement of magnetic fields is essential in sectors such as healthcare, electronics, metallurgy, material science, and energy. Gauss meters, also referred to as magnetometers, are widely used to measure magnetic field strength in Gauss or Tesla units. Like all precision instruments, Gauss meters require periodic calibration to ensure their accuracy, reliability, and compliance with international standards.
FARE Labs has a unique facility for the calibration of Gauss meters/tesla Meters and Magnets, in AC and DC magnetic fields. This facility is covered under the accredited scope as per IO/IEC 17025:2017 by NABL
Our master is directly traceable to the National Physical Laboratory (NPL), India, which is the National Metrology Institute (NMI) of India. This direct traceability guarantees that calibration results are scientifically valid, accurate, and internationally comparable.
DC Magnetic Field Calibration
FARE Labs offers calibration of Gauss meters in DC magnetic fields ranging from 100 Gauss to 10,000 Gauss. This wide range allows testing of instruments used in both low-strength and high-strength applications. In DC calibration, highly stable reference magnets and controlled electromagnets are used to generate known magnetic fields. The Gauss meter under test is placed in the calibrated field, and its readings are compared against the reference values provided by the master system.
This process ensures that the Gauss meter gives accurate readings in practical applications such as the quality control of permanent magnets, testing of industrial magnets, and verification of magnet-based devices. DC calibration is particularly important in research laboratories, manufacturing plants, and industries where permanent magnets are widely used.
AC Magnetic Field Calibration
In addition to DC fields, FARE Labs provides calibration of Gauss meters under AC magnetic fields, covering a wide range of 100 milliGauss (mG) to 2000 Gauss at 50 Hz. This capability is essential because AC magnetic fields are prevalent in environments influenced by alternating current electrical systems, rotating machinery, transformers, and electromagnetic compatibility (EMC) testing.
AC calibration involves subjecting the Gauss meter to a precisely controlled alternating magnetic field generated by calibrated sources. The instrument’s response is evaluated at different levels within the specified range. By doing so, it is verified that the Gauss meter can accurately measure varying magnetic field strengths in real-world conditions where alternating fields are present. This is especially relevant for occupational safety studies, industrial diagnostics, and compliance with electromagnetic exposure standards.
Calibration of Magnets and Electromagnets
FARE Labs’ calibration services are not limited to Gauss meters alone. The laboratory also provides calibration of reference magnets, electromagnets, and industrial magnets. Reference magnets are often used as quick verification standards for Gauss meters in the field, while electromagnets and industrial magnets play crucial roles in processes such as material separation, lifting operations, and medical equipment.
By calibrating these magnetic sources, FARE Labs ensures that they generate the expected field strengths with high accuracy. This enhances the reliability of industrial processes, improves product quality, and supports research applications where magnetic field uniformity and strength are critical.
