Is it possible to use a Lake Shore 450 Gaussmeter or 475 DSP Gaussmeter to measure an HGT-2101 Transverse Hall Sensor?

No, the HGT-2101 sensor is not compatible with any of the Lake Shore Gaussmeters. To use this sensor requires a separate current source that can supply 1mA and a voltmeter to measure the resulting voltage. To determine the field you have to multiply the voltage by the sensitivity of the sensor which you will need to determine yourself.

Understood, Thank you for the information.
Does this model of sensor require a load resistor, if so what resistance is recommended?

Most likely, the sensors do not require a load resistor, however, we do not calibrate them so we cannot answer the question with 100% accuracy. You would need to calibrate the sensor and verify its linearity is no more than +/- 2% between +/-10kG.

From the datasheets I've been able to find it shows the +Ic and -Ic located at opposing corners (same with +/- VH).
Are the polarities of Ic and VH important, or are they interchangeable? I understand if VH is reversed one would see a negative field, but when applying the current is it detrimental to the sensor to apply the current in a reversed polarity?

I would highly recommend that you connect the voltage and current leads with the correct polarity. We have not performed any testing with incorrect connections so we cannot say if it would cause any damage or inaccurate measurements.
