SM - 20 Pocketsize Susceptibility Meter
 |
 |
|
Small, lightweight instrument for fast and sensitive measurement of magnetic susceptibility of rock samples, exposures and drill cores |
|
Designed for field geologists and fast laboratory assays
The SM-20 magnetic susceptibility meter serves for a number of geological and geophysical applications where thu unique sensitivity of 10-6 SI units together with its small , shirt pocket size and light weight are appreciated . The SM-20 is destinated especially for field geologists and for fast laboratory assays for analysis and classification of rock types . Measurements of outcrops , drill cores or other samples allow basic differentiation of rocks ( diamagnetic , paramagnetic and ferromagnetic ) and their precise susceptibility quantification . The original sensor and the new method of signal processing ( based on RISC microcontroller ) guarantee advanced instrument features as a new member . The SM-20 is simply operated using two buttons ( the first one is measurement and the second one for data storage ) . More confortable operating containing point labels , comments and data storage for next processing is available using PC connection . The Li cells supply and the automatic power off function provide a long working time without change . |
