High-Sensitivity and Portable
The RT-1 is a high sensitivity, portable, hand-held Magnetic Susceptibility Meter with both digital and analog readout. The unit is microprocessor (flash ROM) controlled, allowing flexibility in display, auto ranging, auto calibration in free air, and serial output.
Applications
- Geological mapping in mineral & petroleum exploration industries
- Core logging via application of volumetric correction factor for drill-core
- Follow-up magnetic surveys
- Laboratory measurements
Bluetooth Interface
The RT-1 has a bluetooth interface to transfer and store readings on a PC from the unit memory. The data outputs as an ASCII file and includes both the magnetic susceptibility reading and any event flags. Display The RT-1 meter offers both a numeric readout as well as a moving bar graph display, which when combined with the variable pitch audio tone makes it the most functional meter on the market. Memory The RT-1 allows for the storage of over 9800 readings and subsequent recalling through the display or PC interface. Flags can be used to identify individual or group readings.
Readings Mode
RT-1 readings can be made in both continuous or single (step) modes. SI or CGS Units Susceptibility is a dimensionless unit and can either be expressed using SI or CGS units. The RT-1 can be toggled to display values in either SI or CGS, including data already stored in the memory. Auto-Ranging The RT-1 automatically adjusts ranges for maximum reading precision. Magnetic Susceptibility Test Pad The RT-1 comes with its very own Magnetic Susceptibility Test Pad, build directly into the box. On-the-spot calibration checks can now be performed easily, anywhere, anytime.
Magnetic Susceptibility
Magnetic Susceptibility is the intrinsic property that determines the amount of magnetism a rock can have in a given magnetic field. Rocks are composed of minerals which vary in their magnetic susceptibility and magnetite accounts for most of the susceptibility observed. The measurement of susceptibility can be used before magnetic surveys take place to determine which rocks will be detectable magnetically and to what extent. This can be performed in the field on outcrop or on samples in the laboratory. It is also used after drilling to measure drill-core to determine from what rock types and at what depths the observed magnetic responses have originated. In general, rocks and minerals have a typical value of susceptibility. Values can also be related directly to the equivalent percentage volume of magnetite which would produce that value.
