Pocket size Smart Magnetic Sensor

The Hall Meter type SMS-102

Probes for Axial or Transverse magnetic fields

Ranges (AC, DC): 2000.0mT, 200.00mT, 20.00mT, Auto

Analog and Digital output interface

4+1/2 Digit LCD readout

Auto shut-off

The pocket size Smart Magnetic Field Sensor is unique for the features offered. The Sensor will measure axial or transverse magnetic fields up to 2000.0 mT, and can be set for Auto range. However, if one of the 3 manual ranges is selected, an analog output of 2.5 volts for FSD in 1024 steps of each range is possible, making it easy to use with a computer interface.

With the 4+1/2 Digit LCD readout you can use the sensor as a stand-alone magnetic field meter.In addition, the sensor is provided with an USB bidirectional digital interface so you can connect it directly to the serial port of your computer.

An EEPROM inside the probe has been programmed for temperature compensation of non linearity error. Following the patented method the unit removes temperature effects of magnetic sensitivity, resistive residual voltage and also all magneto resistive effects. The unit can also be re calibrated easily if necessary wit help of optional zero gauss chamber.
