Hirst Magnetics GM08 Gauss Meter, DC and 15 Hz → 10 kHz

For measurement of flux density and magnetic field strength of DC,AC and peak magnetic fields in S.I c.g.s units, these two micropressor-controlled menu-driven instruments are the GM07 & GM08 series. Featuring graphical monochrome LCD display, probe polarity inidicator and operating function and units display, it offers a sleek, lightweight and robust design. Complete with a thin semi-flexible probe, it is the ideal instrument for factory floors, on site and laboratory applications.

Hirst Magnetics instruments GM07 and GM08 offer sophisticated measuring functions in a simple use, menu driven, hand held package.

• Retains measurements when powered down
• 0°C to +50°C operating temperature
• Accuracy is specified, at 20°C +/- 1%

Guassmeters 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 Guass and why we call these units Guass meters.

The Transverse Hall Probe is suitable for a wide range of applications where access allows the probe to be orientated to the magnetic field and is ideal for measuring an air gap between magnetic poles, the sensor in the transverse probe is located on the horizontal axis, at the end of the probe.

The Axial Probe is suitable for a wide range of applications where access allows the probe to be orientated to the magnetic field, the sensor in the axial probe is located at the flat end of the probe.
