Our high quality brand RS Pro presents this handheld light weight Gaussmeter, a great instrument for measuring magnetic fields of extremely low frequency (ELF) of 30 to 300 Hz. With a large user friendly LCD display of 3-1/2 digits it has a display range of 20, 200 and 2000. Display units are featured in micro-Tesla and mini-Gauss, with an overload indication (LCD displays 'OL') and a low battery indication. With around 100 hours of battery life, measurement and testing is accurate and easy using the large soft press button panel.

Gaussmeters are a Hall probe, a test current is sent by the meter through the probe. This Hall affect produces a voltage and the meter then records this. Often the highest voltage detected is used or frozen by the meter as voltage fluctuation is common given that magnetic fields are rarely static.

Carl Friederich Gauss born in 1777 developed one of the first devices that could measure direction and strength of a magnetic field. He was a pioneer in this type of study and a great mathematician. He created the system used to measure magnetism and is the reason the modern unit of flux density is named Gauss and why we call these units Gauss meters.
