SM-30 Magnetic Susceptibility Meter

The SM-30 is small (pocket sized) magnetic susceptibility meter. Thanks to the high sensitivity we can measure sediments and rocks with extremely low level of magnetic susceptibility. In addition, we can distinctly measure diamagnetic materials like limestone, quartz and also water.

The SM-30 is controlled by three push buttons. One of them serves to save up to 250 measured values into non-volatile memory and to recall them later. The 251st value (the last measured one) is automatically displayed after SM-30 is switched on. If no button is pressed for 3 minutes, the instrument switches off automatically. The SM-30 has a beeper indicating intervals in which the information from the rock is picked-up.

The SM-30 is powered from two coin-sized lithium batteries. If the instruments is not used too extensively, the batteries may last for years thanks to their low self-discharge.

The SM-30 has 8 kHz LC oscillator with a large size pick-up coil as a sensor. The oscillation frequency is measured when:

• the coil is put to the surface of measured rock
• the coil is removed tens of cm away.

The SM-30 offers six measuring modes. Two of them are basic, two compensate for the linear part of the thermal drift, one is for scanning and one is for averaging. The large number of the memory registers (250) is useful especially when scanning mode is used.

Though the instrument is small, the pick-up coil is large enough in diameter to measure sufficiently high volume.

FEATURES:

HIGH SENSITIVITY 1 x 10-7 SI UNITS
The sensitivity is 100 times better than the competitive instruments.

SMALL SIZE AND LOW WEIGHT
The SM-30 is truly shirt pocket-sized instrument. With dimension 100 x 65 x 25 mm and weight 0.180 kg. SM-30 outperforms competitors 3 times.

LOW NOISE
Thanks to sophisticated signal processing the noise induced in pick-up coil is suppressed well under resolution 1 x 10-7 SI units.

DEEP PENETRATION OF THE SIGNAL
The sensor design enables 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.

SIMPLE OPERATION
Autoranging and three-button control makes the meter the easiest to operate by one hand only. Internal memory can store 250 readings.

SM-20 Magnetic Susceptibility Meter

The SM-20 magnetic susceptibility meter is useful for a number of geological and geophysical applications where the unique sensitivity of 10-6 SI units together with its small, shirt-pocket size and low weight are appreciated.

The SM-20 is designed especially for field geologists and for fast laboratory assays for analysis and classification of rock types or drill core samples. Those measurements allow basic differentiation of rocks (diamagnetic, paramagnetic and ferromagnetic) and their precise susceptibility quantification. The original sensor and the new method of signal processing guarantee advanced features of this kappameter.

The SM-20 is simply operated using two buttons. More comfortable operating including point labels, comments and data storage for next processing is available using PC handling. The Li cells supply and the automatic power-off function provides a long working time without battery change.

FEATURES:

• stores 120 readings
• 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
• unique sensitivity of 1x10^-6SI units
• easy to operate
• autorange, data storage and PC connectivity

KT-6 Kappameter

The KT-6 is the state-of-the-art in Magnetic Susceptibility Meters. The field geologist will find it an indispensable tool as it allows fast, easy and accurate analysis of rock samples.

This portable, hand-held unit can be used in the field by geologists to analyse and classify rock types or core samples.

The data can be transmitted via serial channel RS-232 to a computer to immediate evaluation and graphic representation.

The KT-6 has a maximum sensitivity of 1 x 10-5 SI units - 0.8 x 10-6 cgs units. This allows the unit to accurately measure very low level susceptibility for reliable identification of sedimentary rocks and other weakly magnetised minerals. However, the system is fully auto ranging and can measure up to a maximum of 999 x 10-3SI units without operator adjustment. Thus over the entire operational range, the KT-6 delivers highly accurate and reliable data.

Most susceptibility meters use a ferrite cored coil. This restrict the "depth of penetration" to typically 1 - 3 mm. The KT-6 uses an air-cored coil giving much larger depth penetration - 90% of signal is from the first 20 mm. This means that if sample is being measured that has a rough surface, the KT-6 can be relied upon to give an accurate measurement of the rock's magnetite content. This "depth of penetration" also allows more accurate results from all rock types due to the better volume analysis that occurs with this feature.

• Sensitivity 1 x 10^-5 SI units
• Auto-range
• Real susceptibility automatic calculated
• Air cored coil for more accurate data
• LCD display to read easily in bright sunlight
• Easy to operate - single push-button
• Autoscan mode for core analysis
• Audio indication of relative reading values
• Data memory - 100 readings
• 9V battery, typically 150 hr's battery life
• Output RS-232C
• Real time and date

SM-100 Portable Magnetic Susceptibility Meter

The SM-100 Portable Magnetic Susceptibility Meter is designed for laboratory or field use to measure bulk susceptibility of standard 25,4 mm cores. Small sample fragments can be measured in the pot with inner volume 25 cm3. The SM-100 design reflects the latest in electronic advances and offers unrivalled features:

• single integrated housing incorporating the measurement zone, the electronics and power supply connected to PC
• simple operation without any control knobs.
  

Operation of the SM-100 is straightforward. Typically a small sample in a plastic vessel is placed into the measuring coil for analysis. The SM-20 is controlled by a personal computer. The SM-100 is connected to a PC with a cable to serial RS232 port. Results are available in several seconds and are conventionally stored and displayed on this PC. Flexibility and user friendliness have been the key criteria in the design of the SM-100 software.

Calibration samples are supplied. Checking the calibration takes only a few minutes.

FEATURES:

• HIGH SENSITIVITY 1 x 10-6 SI UNITS
• MEASUREMENT NOT SENSITIVE TO SPECIMEN SHAPE
• BATTERY OPERATED
