 The SM-30 is small magnetic susceptibility meter. Thanks to the high sensitivity it'll measure sediments and rocks with extremaly low level of magnetic susceptibility. In addition, it 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 nonvolatile memory and to recall them later. The 251th 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 lithium batteries CR2430. If the instrument is not used too extensively, the batteries may last for years thanks to their low self-discharge.
- 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 outperformes 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.
- WARRANTY
One-year warranty is included in the price. We offer support and repair service for any instrument sent from any location worldwide. Subsequent customer support is provided.
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 SM-30 offers six measuring modes. Two of them are basic, two are compensating 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.
The instrument is delivered with PC interface cable and a comprehesive Windows software package.
