Check the listing for details. LATNEX® DC Gaussmeter Meter Model DG-800. Condition: New. Listed at 549.99 USD. Product Description:The Model DG-800 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 meter. Flexible probe and battery are included.The product uses a 9 volt alkaline battery.
