The Vector Gaussmeter displays the true magnitude of the field at any location as well as the X, Y, Z components of up to 800 gauss. Also separately displays peak values of X, Y, Z, and magnitude. There is a sound alarm that determines the locations where the field magnitude exceeds user-set threshold. Because magnitude is measured, the orientation of the sensor (E-W, N-S, and up-down) is not important; this is unlike a 1-axis gaussmeter. With the VGM the user can set the alarm to 15 gauss (for example) and it will sound (simultaneous with a red light) whenever the field exceeds 15 gauss for at least 5 milliseconds. Using the meter this way, it is easy to make a map of the 15 gauss line (or for whatever threshold is set) around a strong magnet. When using the alarm, of a steel part can be rapidly scanned to show if any areas exceed the set threshold. Then the “peak hold” function can be interrogated, showing the peak values of X, Y, Z (including polarity) and magnitude that occurred during the scan. Peak hold also has a 5 millisecond response time. The “reset” button resets all peak hold registers to the present values of X, Y, Z and magnitude, which are displayed in real time when the knob is set to “measure.” Offsets can be manually applied to X, Y, and Z, or a “relative zero” can be applied to all three. This subtracts out the field at the time the button was pressed.

Key Features

  • CE Compliant.
  • Includes battery, AC Adapter, alarm output (open/closed switch)
  • Relative zero and manual offset functions independently for X, Y, Z.
  • Sound alarm and light for rapid feedback if the field exceeds threshold you set.
  • Continuous sampling and magnitude calculation every 5 milliseconds; the peak of X, Y, Z and magnitude will be accurate even if they occurred at different times.
  • When set to “Peak Hold”, displays the highest magnitude since the last time “Reset” was pressed. Also remembers and can display peak value of X, Y, Z (including polarity) since the last
  • Displays the magnitude of magnetic field regardless of probe orientation. Also can display X, Y, or Z components.
