This measurer was a magical device used in the United States of America that measured the threat level of exposure of magic to the No-Maj people. It hung in the central foyer of the Magical Congress of the United States of America.

Description[]

The appearance of this device, showing the different colours

It resembled a barometer, had four faces, and black hands. Various colours indicated the threat levels:

  • Zero Threat (Green)
  • Level One: Low Threat (Green)
  • Level Two: Moderate Threat (Green)
  • Level Three: High Alert (Blue)
  • Level Four: Danger (Yellow)
  • Level Five: Severe: Unexplained Activity (Orange)
  • Level Six: Emergency (Red)

There were also counters indicating how many witch hunts have ocurred, how many times witches and wizards had been exposed, and how many times the Memory Charm had been used on non-magical persons.

If the wizarding community in America was close to exposure, the device sounded an alarm informing the Aurors of the impending threat.

Miniature versions that could be placed on a desk were also produced. Auror Percival Graves owned one of these. [1]
