FW Bell 4180 EMF gaussmeter

The Bell 4180 EMF meter is a lightweight and easy-to-use gaussmeter that is suitable for commercial or domestic use. It measures the Extremely Low Frequency (ELF) fields generated by electrical sources such as powerlines, office equipment, household appliances and all types of electronic equipment.

It is a tri-axis gaussmeter, measuring fields from different directions at once or from one direction at a time.

It has an extended bandwidth – and measures fields from 20 to 2000 Hz. This means that it detects a wide variety of frequencies and harmonics.
