Desktop, Handheld and Duo Kits
If you just want to plug a magnetometerAn instrument to measure magnetic flux density (B) or magnetic field intensity (H). More into the USB port of your computer, you need the Desktop Kit. The Handheld Kit, with its optional battery-operated, industrial quality tablet computer, takes the measurement from the lab bench to the field – although of course you can still use the instrument with your computer, too. If you need the capabilities of two probes, the Duo Kit provides a practical and cost-effective package, with or without handheld computer.
