VMR Magnetoresistive Vector Magnetometer
Description:
VMR is a convenient and cost effective means for measuring the vector magnetic field. It is particularly
useful for measurements with nanotesla precision, and while it has excellent stability it does not feature
high accuracy. Due to its low drift, reliable sub-nT resolution is achievable with averaging or using the
built-in filters. It may be used to compensate for heading errors in precision optical magnetometers.
Specifications:
- 3 axis magnetoresistive sensor
