SatisGeo KM-7 is a compact, easy-to-use, and robust handheld instrument designed for quick and easy magnetic susceptibility measurements. Its features make it an indispensable tool in field conditions and laboratory research. The KM-7 magnetic susceptibility meter is suitable for quick orientation measurements of the magnetic properties of rocks and for selecting suitable specimens for further, precise laboratory studies. It can also be used to measure the magnetic properties of drill cores.

  • High resolution
  • Excellent accuracy
  • Wide measuring range
  • Single & Scan mode of operation
  • Measuring PIN
  • GPS connection via Bluetooth

  • Mineral exploration
  • Measuring on drill cores
  • Archaeology

  1. SINGLE
    • For individual measurements on the sample.
    • It performs three measurement steps (air – sample – air) for maximum compensation for temperature effects.
    • The GPS position is automatically stored if the GPS is active.
  2. SCAN
    • For indicative measurements of the magnetic susceptibility distribution.
    • It measures approximately 3 times per second and displays the values in real-time (without storage).
  3. REMOTE SCAN
    • Designed especially for drilling cores.
    • Transmits and stores data to the computer 5 times per second with averaging capability.

  • FLAT – For measurements on flat surfaces with a sufficiently large sample size. For small samples, the magnetic susceptibility value may not be correct.
  • PIN – The sensor is equipped with a special additional spacer pin for uneven surfaces.
  • CORE – For measurement on drill cores, with core diameter adjustment. Not suitable for halved cores.

Size 165 x 68 x 28 mm
Weight 250 g including battery
Temperature  range -20°C to +60°C
Power Consumption 8 mA without backlight and Bluetooth
Communication USB 2.0, Bluetooth. Bluetooth can be used to connect to Bluetooth GPS.
Robust construction dust and water-resistant, ideal for off-road use

The KM-7 allows communication with an external device using Bluetooth wireless technology. This enables the KM-7 to connect to an external GPS receiver that can send NMEA messages using the Bluetooth Serial Port Protocol (SPP). When the KM-7 is connected to such a GPS receiver, the sample position is stored with its value.

The instrument is calibrated for ideal conditions, where the measurement is performed on a smooth sample of known magnetic susceptibility that exhibits homogeneous and isotropic properties. The dimensions of the sample are sufficiently large relative to the size of the sensor and can be considered a half-space.

  • 1 x Leather case
  • 1 x PIN for measuring on uneven surfaces.
  • 1 x Manual
  • 2 x AAA batteries
  • 1 x USB cable
  • 1 x USB FLASH with operator program
