The Goptica 3-Axis Hall Probe is a handheld teslameter designed for high-precision magnetic field measurement.
It simultaneously measures the magnetic field components in three orthogonal directions in space, giving you a comprehensive, intuitive understanding of the true distribution and variation of the magnetic field.
Featuring a portable all-in-one design, the instrument comes with a high-refresh-rate display on the main unit. The probe connects to the main unit flexibly via cable, making it easy to handle on-site field measurement, mobile inspection, and in-laboratory installation and commissioning. Whether for scientific instrument development, industrial equipment testing, or electromagnetic environment assessment, we deliver reliable and stable measurement performance.
