Mag-01H DI

This precision measurement system enables accurate measurement of the Earth’s magnetic field declination and inclination in magnetic observatories or in the field.

The system comprises a single axis fluxgate magnetometer (Mag-01H), a fluxgate probe (Mag A probe), and a WILD T1 6″ steel-free theodolite. A steel-free tripod is available for mobile surveys. The Mag A probe offsets are adjusted electronically to ensure the highest accuracy during declination and inclination observations (using the null-method), with angular values estimated easily to 2 seconds on the Wild T1.


  • High accuracy due to 6 arc second-precision theodolite, and magnetometer offering 0.1nT resolution
  • Electronic adjustment of offset
  • Non-magnetic theodolite
  • Long term stability
  • Battery power
