The KT-10R Plus S/C Magnetic Susceptibility/Conductivity Meter with rectangular coil is available, in addition to the KT-10 Plus S/C with circular coil.  Both configurations allow users to simultaneously measure the magnetic susceptibility and conductivity of rock samples or drill cores.   Both configurations are also equipped with a host of features that include an extended magnetic susceptibility measurement range, the ability to present users with an iron ore concentration estimate, input depth correlation information and a correction for split and full cores.

Major Benefits

Four Instruments in One

The KT-10 Plus S/C and KT-10R Plus S/C are four-in-one instruments that can be used in the following configurations:
– Magnetic susceptibility only (like a KT-10 v2)
– Direct iron concentration measurement estimates (like a KT-10 Plus v2)
– Conductivity only (like a KT-10 C)
– Magnetic susceptibility and conductivity simultaneously

New Rectangular Coil Available

The KT-10 Plus S/C is now available in two different coil configurations: the KT-10R Plus S/C with Rectangular Coil or the standard KT-10 Plus S/C with Circular Coil. The rectangular coil is beneficial for measuring core samples with small diameters as they do not need to be removed from the core box for measurement. The circular and rectangular coils are not interchangeable.

Direct Iron Ore Concentration Measurement Estimates

Direct iron ore concentration measurement estimates can be obtained from the meter’s display by using the pre-installed calibration curve.

High Magnetic Susceptibility Sensitivity and
Dynamic Range

The KT-10 Plus S/C and KT-10R Plus S/C have a maximum sensitivity of 1 x 10-6 SI Units on smooth surfaces for magnetic susceptibility measurements. They are also equipped with an increased measurement range of up to 10 SI units, allowing users to measure and analyze samples with a high magnetite content.

Wide Range Absolute Conductivity Meter

The KT-10 Plus S/C and KT-10R Plus S/C have been calibrated using a multi-point algorithm to ensure accurate measurements between inductive and galvanic methods. They can measure conductivities from 1 to 100,000 S/m, while maintaining a sensitivity of 1 S/m.

Measure in SI or CGS and S/m or Ω.m Units

Users can obtain magnetic susceptibility measurements in either SI or CGS units; while conductivity measurements can be in either S/m or Ω.m units.

More Benefits

Depth Correlation

The KT-10 Plus S/C and KT-10R Plus S/C feature large internal memories that allow the user to input information to correlate every core measurement to its depth. The user can enter information such as borehole I.D., box number, the number of rows in a box, start and end depths, as well as depth intervals. In the Scanner mode, depth intervals can be recorded with the push of a button. All readings between depth intervals are interpolated into the data for reference.

Split and Full Core Corrections

The KT-10 Plus S/C and the KT-10R Plus S/C includes a real time diameter correction for both split and full cores. The user can select from a range of drill rod diameters (AQ, BQ, NQ, HQ and PQ) or non-standard ones from 2.4 to 12 cm.

Fast and Accurate Scanning

The KT-10 Plus S/C and KT-10R S/C scan 20 readings per second and stores 4 averaged readings during the same period.

Pre-Installed Calibration Curve

One calibration curve is standard in the KT-10 Plus S/C and KT-10R Plus S/C’s firmware. This calibration curve is based on magnetite with different concentrations.

Programmable Calibration Curve Capability

Users can also program additional calibration curves which are specific to the samples and cores being measured. By taking a number of magnetic susceptibility measurements from a range of samples with known concentration values, users can program their own calibration curves using the GeoView Software. The new calibration curves can then be transferred to any KT-10 Plus S/C or KT-10R Plus S/C.

Flexibility in Transferring Calibration

Users can transfer their own calibration curves between KT-10 Plus S/C and KT-10R Plus S/C meters with the use of the GeoView Software.

Large Memory

The KT-10 Plus stores up to 3,000 readings in its internal non-volatile memory. Average readings and standard deviation are also stored. The operator can record up to one minute of comments associated to each specific reading through the KT-10 digital voice recorder.

Fast and Accurate Scanning

The KT-10 Plus scans 20 readings per second and stores 4 averaged readings during the same period. The operator can also add markers to the data set to identify the location of those measurements.

Improved PC Interface

The KT-10 Plus includes GeoView, a multi-platform software which allows the operator to download and visualize the KT-10 Plus data with the click of a few buttons. GeoView can also play back the voice notes stored along side the readings, change the KT-10 Plus’ settings and transfer the data to a spreadsheet. It also allows the operator to view or export GPS paths into a Google Earth compatible format.

Other Benefits

Large Memory

The KT-10 Plus S/C and KT-10R Plus S/C feature a 4 GB internal memory that can store up to 4,000 total records. Users can take up to 4,000 scanner measurements with up to 480 data points per record, or 4,000 discrete measurements with 120 seconds of voice notes per reading. Discrete and scanner records can be combined to total 4,000.

Quality Control (QC) Parameters

The KT-10 Plus S/C and KT-10R Plus S/C provides users with the ability to assess data quality. Along with the measurement results, a user can obtain data averages and standard deviation values in measure mode, or data averages and maximum values in scanner mode.

Uneven Surface Measurements

The KT-10 Plus S/C can be used with a pin for uneven surface measurements, or without a pin when applied on a flat surface. It also automatically corrects and displays the true magnetic susceptibility. The KT-10R S/C is not supplied with a pin as one of its main uses is for measuring core samples.

Flexible PC Interface

Both configurations include GeoView, a multi-platform software which allows the user to download and visualize the data. GeoView can also play back the voice notes stored along side the readings, change the meters’ settings, transfer the data to a spreadsheet and view or export GPS paths into a Google Earth compatible format.

Upgrades and Support Available via the Internet

The KT-10 Plus S/C and the KT-10R Plus S/C can be both upgraded and supported remotely through the internet. Users are also able to download the latest firmware upgrades to receive new features as they become available. The KT-10 Plus S/C and the KT-10R Plus S/C can be upgraded to a KT-10 Plus S/Cx. The “x option” (or extended measurement range) will increase the meter’s conductivity measurement range to 1 – 200,000 S/m.

Bluetooth and USB Connectivity

The KT-10S/C and the KT-10R S/C come standard with both Bluetooth and USB connectivity. Bluetooth capabilities allow users to download the meter’s data wirelessly and/or connect to a Bluetooth enabled GPS unit to store GPS coordinates along with the readings. USB communication is also available for transferring measurements and voice comments from the meter to a PC, as well as firmware upgrades and parameter settings.

GeoView PC Interface Software

Data Management

GeoView is a multi-platform software that allows users to organize their KT-10/KT-10R v2 data by date and serial number. It also facilitates the transfer of data from the KT-10/KT-10R v2 to a personal database for further correlation and interpretation. GeoView is compatible with all Windows 32 or 64 bit operating systems.

As presented below, averaged readings are grouped together with records (containing date, time, value, voice notes and optional GPS positions) in one convenient location. Users can also add new column headers to enter additional information specific to the data collection.


Data Visualisation

A numerical display allows users to quickly review the field data, while a graphical display aids in the interpretation of scanner data.

As shown below, the scanned data is displayed in a graphical mode. The use of markers can assist operators to orient the readings to a physical location.

Upgrade to Extra High Conductivity

The KT-10 Plus S/C and KT-10R Plus S/C have a standard measuring range of 1 to 100,000 S/m. As an option, this range can be increased to 200,000 S/m. This KT-10 Plus S/Cx and KT-10R Plus S/Cx upgrade can be performed via the internet using the GeoView software with a PC.

Conductivity Reference Pads

Three reference pads with different conductivity ranges (low, medium and high) are available for measurement verification. Although there are three different ranges, each pad has a number of common parameters:

High homogeneity of conductive elements
Only diamagnetic materials are used eliminating magnetic
susceptibility influence
Use of a sealing compound to block transfer of humidity
Optimal pad dimensions to reduce size effect
Smooth surface to optimize contact and ensure high
accuracy of readings

The low range pads are made of semi solid gels, while the middle and high range pads are of a proprietary mixture of ceramics. Each pad has been tested independently using different methods for measuring conductivity (AC and DC bridges plus impedance bridges).
