Why Choose the AP002 Axial Probe?

The Axial Probe is suitable for a wide range of applications  where access allows the probe to be orientated to the magnetic field as shown in the diagram. The axial probe is for readings within the range of 0- ±3.00 T to ±3.00 mT or ±30.00 kG to ±30.00 G. If you require a more sensitive measurement, please see the AP002HS High Sensitivity Axial Probe.

The sensor is located in the flat end of the sensor. If you are measuring in an air gap between magnetic poles, you will need a Transverse Probe.
