The KT-20 meter is a handheld console that measures the magnetic susceptibility of a geological sample or core in either SI or CGS units. A range of sensors with different shapes and frequencies can be used with all KT-20 models. Users can interchange the sensors on the console, allowing the KT-20 to be adapted to different sizes and types of samples, or used in various applications.
SENSORS SOLD SEPARATELY (see item links below). A wide range of sensors with different shapes and frequencies can be used with all KT-20 models. Users can interchange the sensors on the console, allowing all models of the KT-20 to be adapted to different sizes and types of samples, or used in various applications. Please see information below for available sensors.
KT-20 CONSOLE STANDARD FEATURES:
The KT-20 console includes a number of built-in features to increase the amount of information that can be added to a measurement record. These features include a GPS receiver to obtain coordinates of the measurement, digital camera to photograph the sample, a microphone to record voice notes, and a virtual keyboard to enter text notes.
· View data in real-time on the large KT-20 trans-flective colour LCD screen. View any stored records directly on the large KT-20 screen.
· Three modes of operation: single measurement, continuous scanner, and borehole to correlate measurement results to their depth in the borehole.
· Split and full core corrections for standard drill rod diameters (AQ, BQ, HQ, NQ and PQ) and non-standard sizes (2.4 cm to 12 cm).
· The KT-20 console features 16 GB of memory, built-in GPS receiver, digital camera, microphone and virtual keyboard for users to include additional information with measurement results.
The KT-20 console comes with 2 rechargeable Li-ion batteries with charger, a USB cable, GeoView 2 software, and a rugged transportation case.
APPLICATIONS
A modular design and interchangeable sensors give the KT-20 the flexibility to measure a wide variety of types and sizes of samples, or adapt the console for different applications.
· Drill Core – Curved sensors for measuring cylindrical core. Their unique shape permits the entire surface area of the sensor to make contact with the core sample, improving both the sensitivity and repeatability of the measurements. Use the IP/Resistivity Module to measure the sample’s chargeability and resistivity.
· Prospecting – Use the KT-20 in the field for prospecting. Circular sensors are utilized for measuring large samples, like outcrop. The 10 kHz single-frequency circular sensor features a pin mode that aids in measuring samples with uneven, rough surfaces.
· Powders and Chips Samples – Use any circular or rectangular sensor to collect measurements on powders, rock chips and other loose samples. These types of samples should be formed into a bulk mass, with a surface area larger than the sensor, and at least 2-inches thick.
· Environmental Investigations – The 3F-32 large diameter sensor has a greater depth penetration than the single- and dual-frequency sensors. Use the 3F-32 to map soils, or in agricultural applications.
· Archaeology – The 3F-32 large diameter sensor is able to map the magnetic susceptibility and conductivity of soils, or detect shallow targets. Smaller sensors can be used to collect additional information on artifacts.
GeoView 2 Software
GeoView 2 is an easy-to-use data management and visualization software program that is compatible with all Windows operating systems.
It enables users to download, store and view a KT-20’s data on a PC and export it to Excel. Data is organized by date, or by instrument serial number when there are data from multiple instruments. Additional information collected can be viewed in GeoView 2, including averaged readings, standard deviation, text and voice notes, pictures and GPS coordinates. GeoView 2 is also a data visualization tool. Numerical values from discrete measurements are displayed in a table format; data from scanned and borehole mode measurements are displayed as a graph. Data from the borehole mode will show measurements from specific depths.
**How often should I calibrate my Meter?
All units are factory calibrated before shipping to you. This means that as long as the meter does not suffer from serious physical damage (i.e. the measuring coil gets broken), periodic calibration should not be required. If you are in doubt about your unit's accuracy, you can easily calibrate it for magnetic susceptibility measurements yourself.
Option 1 - Purchase a set of magnetic susceptibility calibration pads for ultimate peace of mind.
Option 2 - Use a rock with a flat surface and thickness of at least 2 inches, which is homogeneous in its magnetic susceptibility. Draw a circle on the rock to make sure you always take the measurement at the same location, same angle and ideally same temperature (if possible).
