Please read the following table for sensor specifications. 



Measurement Ranges

±5 mT and ±130 mT 

3 channels, for the measurement of magnetic field in X, Y and Z direction 

Note: The ±5mT range has an absolute measurement span of ±4.6mT to ±5.2mT. This is unique to each sensor and cannot be adjusted. 


±5% of reading


0.1 mT on ±130 mT device

0.15 µT sensitivity on ±5 mT device

Maximum magnetic field stress rating:

1,000 mT (1 T), above this level may cause permanent damage  

Fastest logging speed

±5 mT range: interval of 10 ms = 100 samples per second

±130 mT range: interval of 1 ms = 1,000 samples per second
