SM 150L Portable Magnetic Susceptibility Meter

SM150L magnetic susceptibility meter is designed to measure sample with volume up to 25 cm3. It is calibrated for cylinder with diameter 25,4×22 mm. Adjusting frequency and field intensity broaden information of measured sample. Thanks to built-in scales we can measure mass susceptibility too.

Operation is straightforward. Sample in the plastic pot is placed into measuring coil for analysis, which is carried out under instruction from personal computer. The SM150L is connected to PC with cable to USB port. The result is available in several seconds and is conventionally stored and displayed on this PC. Flexibility and user friendliness have been the main criteria in the design of the SM150L software.

The instrument is calibrated in the factory on 16 kHz range by means of coil.Then auxiliary standard with 16 g Gd2O3 is measured on all ranges.Value from 16 kHz range is then used for adjusting remaining ranges to display 16 kHz value too. Gd2O3 standard is supplied with the instrument.
