A valuable tool for the researcher or experimenter in magnetism.
Handy low-cost meter measures from < 1 up to 10 gauss for full scale reading. Allows you to check polarity and obtain relative field strength readings. Checks magnetic pulsers, normal fixed magnets, and potential fields in a magnetically active area.
Device measures 2-1/4" diameter at outer lip (2" diameter base) x 1-1/8" deep. Weight is 1.4 ounces. Polarity indicator noted on rear of the unit. Center scale calibrated allows you to quickly determine strength and direction of polarity.
Does not require batteries and is ready to use.
