KT-10 C and KT-10R C Conductivity Meters


The KT-10 C & KT-10R C are handheld instruments that measure the conductivity of rock samples and drill cores.  They include benefits such as the ability for users to input depth correlation information, a correction for split and full cores, as well as a large internal memory.  They can also be upgraded to either a KT-10 S/C or KT-10 Plus S/C Magnetic Susceptibility and Conductivity Meter.

Major Benefits

New Rectangular Coil Available

The KT-10 C is now available in two different coil configurations: the KT-10R C with Rectangular Coil or the standard KT-10 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.

Wide Conductivity Range

The KT-10 C & KT-10R C can measure conductivities from 1 to 100,000 S/m, while maintaining a sensitivity of 1 S/m.

Optional Extended Conductivity Range

An extended measurement range is available as an option that increases the KT-10 C & KT-10R C’s measurement range from 1 to 200,000 S/m.

Absolute Conductivity Meter

The KT-10 C & KT-10R C have been calibrated by using a multi-point algorithm to ensure accurate measurements between inductive and galvanic methods.

Depth Correlation

The KT-10 C & KT-10R C’s large internal memory 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 C & KT-10R 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.

Measure in S/m or Ω.m Units

Users can obtain conductivity measurements in either S/m or Ω.m.

Additional Benefits:

Upgrades and Support Available via the Internet

The KT-10 C & KT-10R 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. Both instruments can be upgraded into a KT-10 Cx or KT-10R Cx for an increase measurement range for conductivity, or to a KT-10 S/C or KT-10 Plus S/C to allow the user to read both magnetic susceptibility and conductivity measurements simultaneously.

Fast and Accurate Scanning

The KT-10 C & KT-10R C scan 20 readings per second and store 4 averaged readings during the same period.

Large Memory

Both configurations 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 C/KT-10R 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.

Flexible PC Interface

The KT-10 C/KT-10R C 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.

Bluetooth and USB Connectivity

The KT-10 C & KT-10R 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. 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.

Large LCD Display

A high contrast LCD is utilized for the display of the conductivity readings. It also serves as the interface for operating the instrument.

Variable Audio Capability

The KT-10 C & KT-10R C’s speaker allows the user to monitor the variations in the measurements with a variable audio sound while in Scan mode.

Rugged and Reliable

The KT-10 C & KT-10R C meet IP65 standards and are therefore protected against dust, rain or conditions with high humidity. Its compact size and ergonomic design make it easy to carry and operate.

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 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.

KT-10 C Options

Upgrade to a KT-10 Cx & KT-10R Cx

The KT-10 C & KT-10R C are upgradeable to a KT-10 Cx &  KT-10R Cx to increase their measurement range to 1 – 200,000 S/m. This upgrade can be performed via the internet using the GeoView software with a PC.

Upgrade to a KT-10 S/C or KT-10 Plus S/C

The KT-10 C & KT-10R C can be upgraded to the KT-10 S/C or KT-10 Plus S/C, allowing users to read both magnetic susceptibility and conductivity measurements simultaneously. The KT-10 Plus S/C provides users with the added benefit of being able to obtain iron ore concentration estimates from samples or drill cores. This upgrade can be performed via the internet using the GeoView software (instrument must be connected to a PC either with USB or Bluetooth).

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).
