SM30 Magnetic Susceptibility Meter is a handy, pocket-sized geophysical instrument that enables you to measure the magnetic susceptibility of material. This includes core samples, rocks, and minerals. Featuring high sensitivity which allows you to measure even low-value rocks and sediments. It features an 8 kHz LC oscillator with a large-size diameter coil pickup sensor. A sensitivity of 1×10-7 SI UNITS and can collect 90% of its signal from the first 20 mm of the rock. Suitable for various mineral exploration applications whether within a field lab, on-site in the field, or at a drilling rig.

SM30 Magnetic Susceptibility Meter is a handy, pocket-sized geophysical instrument that enables you to measure the magnetic susceptibility of material. This includes outcrops, core samples, mineral ores, and rocks. Despite its small size, it boasts high sensitivity which allows you to measure even low-value rocks and sediments. Furthermore, it can also distinctly measure diamagnetic materials such as limestone, quartz, and even water.

 

Ease of Use

The unit features an easy-to-use layout, with three push buttons to control it. One of them serves to save up to 250 measurements into nonvolatile memory. The last measurement value is automatically displayed after SM30 is switched on. The SM30 has a ᅠbeeper indicating intervals in which the information from the rock when it detects a reading. In addition, the instrument also comes with an auto-ranging function. Thanks to the large size coil and sensitivity of its sensor, readings take less than 5 seconds in the field.

 

Technical Specification

Being so small, the SM30 is powered simply by two-coin lithium batteries, specifically, CR2430. If the instrument is not in use extensively, these have the ability to last for years, due to their slow discharge rate. Despite this, the instruments boast an impressive high sensitivity of 1×10-7 SI UNITS. More than many other larger models on the market. This is thanks to the 8 kHz LC oscillator with a large-size diameter coil pickup sensor. In addition, this sensor’s design is intended to provide a deep penetration signal. Which enables you to get 90% of its signal from the first 20 mm of the rock. This feature allows more accurate readings on uneven surfaces of all rock types. It also comes with six measuring modes, four of which suppress linear part of the thermal drift.

 

Exporting Data

Users can export data from the instrument to computers and laptops, via the USB cable. In addition, a USB drive which comes with it, also includes the SM30W software. This program can connect to the device and export the data. It can then visualize any data on the device, into a chart and can test for noise and temperature stability of the instrument

 

All in all, the SM30 Magnetic Susceptibility Meter is truly a pocket-size, highly functional geophysical instrument for field and exploration geology use. Measuring only 100×65×25 mm and coming in at a weight of 180 grams.
