HCS100Hall effect measurement system with Halbach configuration

The HCS100 uses a magnet in Halbach configuration (permanent magnet in donut configuration), in order to apply a DC or AC magnetic field to the sample. The Halbach array coil has a lower intrinsic inductance than conventional coils. The Halbach array coil can therefore produce a relatively high magnetic field at a lower inductance and hence a higher power factor compared to conventional coils.
This system is therefore a powerful tool for the characterization of demanding samples, as noise measurements can easily be suppressed in most cases.

• AC/DC current

SPCBSample holder for HMS series

These easy probe holders are composed of a small pcb on which the sample under test is held using spring clips.
The sample to measure is square with a pretty small size.

- Four individually adjustable gold plated spring needles allow a good electrical contact on each corner (may need a point of Indium solder deposited for better contact, not always necessary, depends on sample material).
- No soldering necessary
