DC Gaussmeter GM1-HS with Aluminium Carrying Case
The Model GM1-HS measures the strength and polarity of magnetic fields up to 799.99 gauss. The thin sensor is at the end of a 100 cm flexible cable. The sensor tip is also flexible and can be bent for a variety of situations. The sensor can be held against the surface of a steel part to check for residual magnetism, or it can be bent into an “L” shape to measure inside a DC Solenoid. This meter has a resolution of.01 gauss. It is also used to map fields from large magnets. The meter has immediate turn-on and updates 4 times a second. There is no setup required, making this the fastest gaussmeter available. This is a 1-axis
