Magnetic field measuring device that does not violate regulations [Compliant with new JIS standards]
Small Magnetic Field Meter TMM-3
With the push of a button, you can easily and accurately measure the magnetic field around power equipment. It is compact, lightweight, and can be held with one hand, while also being durable.
The 3D Magnetic Field Meter TMM-3 is a portable measuring device that can measure the intensity of magnetic fields generated by power equipment and other sources. The ministerial ordinance that establishes technical standards for electrical equipment requires measurements to be taken with devices that comply with JIS standards. In response to the replacement of the JIS standard with JIS C 1910-1:2017 in 2017, we developed the TMM-3 to comply with the new JIS. It is scheduled to be released in May 2025. Recommended for those who: - Want to measure magnetic field intensity using devices and methods that comply with legal regulations for electrical equipment. - Are looking for a portable and easy-to-operate measuring device. - Want to investigate magnetic fields with a high-precision and reliable measuring device. Our magnetic field meters have been in sales for over 30 years and have been used by customers such as power companies, manufacturers, research institutions, and construction companies. Features: - Complies with JIS C 1910-1:2017 - CSV output possible via PC communication function - Dedicated range for commercial frequencies - IPX7 waterproof function - Records maximum values within any measurement time - Calibration tests conducted in-house based on JIS standards Feel free to contact us through our company website (registration not required).
