GM09-1 is a single-axis gaussmeter featuring touch-screen interface and rechargeable Li-ion battery compatible with the extensive range of Hirst Hall sensor probes. Built-in “App” modes ensure standard tests and measurements can be carried out with ease and minimal effort. Data-logging features allow the retrieval of data using a simple USB interface, no additional software is needed as the GM09 appears as a USB mass storage device.

Key features

• A hand-held touch-screen general purpose gaussmeter (for determining magnetic field strength) with a range of built in application modes to make routine testing more user-friendly.
• GM09 appears as a USB mass storage device when connected to a computer or device and no software is needed to access the stored (time stamped data) in standard .CSV file formats.
• Application modes include (dependant on probes used):
  • Magnet testing - pass/ fail within user defined bands with polarity.
  • Magnetic Field testing – for standard and stringent safety levels or user defined pass / fail criteria.
  • Residual magnetism testing – for standard levels or user defined pass / fail criteria.
  • Fit-to-Fly testing for magnetic materials against IATA (and FAA guidelines) tests, this requires a High Sensitivity probe.
  • Food Magnet Extractor testing with standard settings (8, 10, 12 kG) plus user defined pass / fail criteria.
  • Occupational safety mode testing based on 1998 ICNIRP guidelines with DC testing using standard probes and AC testing using high sensitivity probes for AC fields up to 6kHz.
• Rechargeable Lithium-ion battery with USB-C compatible charging (wall-plug or computer charging)
• Easy to operate 3.5” multi-colour touch screen 320x480 px with backlight.
• Intuitive easy to use menus with on-screen help and a dedicated knowledge base support website.

The GM09 Gaussmeter is the best device for those needing to measure magnetic field strength and magnetic flux density regularly on a daily basis with the simplest data access of any Hirst gaussmeter with built in application modes to make standard tasks even easier.

Some example applications include:

• Magnet polarity measurements, magnet strength testing. Testing Magnet calibrations.
• Production testing : computer disk drive actuators testing, loudspeaker air gaps, electric motor air gaps.
• Transformer Stray Field measurements.
• Magnetic field strength testing for food industry separators.
• Verifying compliance with IATA, IACO and FAA regulations on magnetism from packages to be shipped by air (High sensitivity probes only).
• Goods inward and Quality Assurance Inspection.
