KT-20 Magnetic Susceptibility/Conductivity Meters

KT-20 Magnetic Susceptibility and Conductivity Meter

The KT-20 is a handheld instrument capable of measuring the magnetic susceptibility, conductivity or density of a sample. Its modular design provides users the ability to employ different sensors that are of an optimal frequency for either magnetic susceptibility or conductivity measurements. The sensors are available in circular and rectangular designs and can easily be interchanged, allowing the KT-20 to measure smaller or larger sized samples or cores.    Density measurements can also be obtained from the KT-20 providing more information about the sample.   A picture, audio note, text note and GPS coordinates can also be added to the measurement to increase the amount of information one can attach to each record to improving archiving

Density Measurements

Sensors

• Five sensors are available in dual and single frequencies to provide certain benefits for either magnetic susceptibility or conductivity measurements.

• State of the art design enables sensors to be easily interchanged.

• Circular and rectangular sensor designs available to adapt the KT-20 to large and small sized samples (note: 10 kHz single- frequency sensor is only available in a circular design).

  

• 10 kHz single-frequency sensor includes a pin for measuring rough or uneven surfaces.

• Each KT-20 model requires one sensor for operation.  Multiple sensors can be purchased with the KT-20 or added afterwards.

• IP/Resistivity Sensor and 3F-32 Triple-Frequency Large Diameter Sensor will become available in late 2015.

Magnetic Susceptibility Calibration Pads and Conductivity Reference Pads

Magnetic Susceptibility Calibration Pads

Two calibration pads with low or high susceptibility values are available to verify the KT‐20’s magnetic susceptibility measurements. These calibration pads can also be used to recalibrate the magnetic susceptibility readings.

Conductivity Reference Pads

Three reference pads are available to verify the KT‐20’s conductibility measurements.    These reference pads are available with low, medium or high conductivity values. Each pad has been independently tested using different methods for measuring conductivity (AC, DC and impedance bridges).
