Hirst GM09 Series Gaussmeters

Hirst GM09 Series Gaussmeters

Overview

The GM09 Series Gaussmeters are the best devices for those needing to measure magnetic field strength and magnetic flux density regularly on a daily basis. The GM09 Series Gaussmeters are comprised of two models, GM09-1 and GM09-3, featuring touch-screen interfaces and rechargeable Li-ion battery compatibility, with an 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.
  • Rechargeable Lithium-ion battery with USB-C compatible charging (wall-plug or computer charging)
  • Easy to operate 3.5” multi-color touch screen 320x480 pixel with backlight.
  • Intuitive easy to use menus with on-screen help and a dedicated knowledge base support website.

Applications

  • 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) (GM09-1 only).
  • Goods inward and Quality Assurance Inspection.

GM09 Series Models

GM09-1 

Features

  • An extensive range of Hirst Hall single-axis sensor probes
  • Application modes include (dependent 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.

GM09-3

Features

  • Hirst three-axis Hall sensor probe only
  • Display of magnetic field in cartesian coordinates (Bx, By, Bz and B) or polar coordinates (B, θ, Φ)
  • Application modes include:
    • Magnet testing - pass/ fail within user defined bands with polarity
