Measure weak DC magnetic fields up to several times the strength of the Earth's field!
Manufactured in the USA, the DC Milligauss Meter allows you to take very precise magnetic measurements in small areas or with high gradients, when necessary. It features a small magnetoresistive sensor which represents a major improvement in both cost and stability in comparison to uncompensated fluxgate magnetometers.
Three offset knobs allow you to add or subtract up to 600 milligauss, which is helpful if you are using the 1999.99 range in a high field (over 200 milligauss). This meter is usually used when all three offset knobs are set to zero and the milligauss range is set to 1999.9. This will then allow the meter to read the actual magnetic field up to +/- 1999.9 gauss.
It also has an extra digit compared with most portable magnetometers and updates 3 times per second. The high stability of the meter (+/- .01 milligauss), allows for stable detection of small changes in a large background field.
The sensor is at the end of a 4ft eight-wire cable and is able to detect the component of the field that's in the same direction as the cable is pointing. The meter reads negative when pointing toward the south pole of a magnet and positive when pointing north.
The meter comes with a NIST-traceable certificate of calibration, a replaceable 9-volt alkaline battery (life about 25 hours) and a mains adaptor.
Dimensions Approx: 175 x 100 x 40 mm
