Unlike metal detectors, a magnetometer signal is not attenuated by rock, dirt, mud or water, so targets can be detected at great depth. (If D is the diameter of a mass of magnetizable material, the EM2 can detect it as deep as 40 times the diameter D, whether the mass is specifically magnetized or not.) It is the lightest weight and lowest cost magnetometer available which can reliably measure differences down to 1 nT from point to point. (Because of random fluctuations in the Earth field due to the ionosphere, 1 nT is about the finest usable resolution.)<br \/>\n\u5730\u7403\u4eea\u6a21\u578bEM2\u63aa\u65bd\u53d8\u5316\u5c0f\u7684<a href=\"https:\/\/www.bihec.com\/alphalab\/tag\/%e4%bd%8d%e7%bd%ae\/\" title=\"View all posts in \u4f4d\u7f6e\" target=\"_blank\">\u4f4d\u7f6e<\/a>\u5728\u5730\u7403\u78c1\u573a\u4e0e\u78c1\u76f8\u5173\u63a9\u57cb\u7fa4\u4f17\u3002\u4e0e\u91d1\u5c5e\u63a2\u6d4b\u5668\u4e0d\u540c\u7684\u662f\uff0c\u78c1\u529b\u8ba1\u7684\u4fe1\u53f7\u662f\u4e0d\u8870\u51cf\u7684\u5ca9\u77f3\uff0c\u7070\u5c18\uff0c\u6ce5\u6d46\u6216\u6c34\uff0c\u6240\u4ee5\u76ee\u6807\u53ef\u4ee5\u68c0\u6d4b\u5230\u5728\u5f88\u5927\u7684\u6df1\u5ea6\u3002\uff08\u5982\u679cD\u662f\u5927\u91cf\u78c1\u6027\u6750\u6599\uff0c\u76f4\u5f84\u7684EM2\u80fd\u63a2\u6d4b\u5230\u6df140\u500d\u76f4\u5f84D\uff0c\u65e0\u8bba\u662f\u5927\u4f17\u7279\u522b\u662f\u78c1\u6027\u3002\uff09\u5b83\u662f\u91cd\u91cf\u6700\u8f7b\u3001\u6700\u4f4e\u7684\u6210\u672c\u80fd\u53ef\u9760\u5730\u6d4b\u91cf\u78c1\u529b\u4eea\u5dee\u5f02\u964d\u52301\u65b0\u53f0\u5e01\u7684\u70b9\u5bf9\u70b9\u3002\uff08\u7531\u4e8e\u7535\u79bb\u5c42\u7684\u968f\u673a\u6ce2\u52a8\uff0c1\u65b0\u53f0\u5e01\u662f\u5173\u4e8e\u6700\u597d\u7684\u53ef\u7528\u5206\u8fa8\u7387\u3002\uff09<\/p>\n<p><strong>Magnetometer min. 1 nT | EM2 \u81f3\u5c111\u65b0\u53f0\u5e01| EM2\u78c1\u5f3a\u8ba1<\/strong><\/p>\n<br><div class=\"tagcloud\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Magnetometer min. 1 nT | EM2 \u81f3\u5c111\u65b0\u53f0\u5e01| EM2\u78c1\u5f3a\u8ba1 Description \u63cf\u8ff0 The Earth Magnetometer Model EM <\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[25],"tags":[],"_links":{"self":[{"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/posts\/29438"}],"collection":[{"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/comments?post=29438"}],"version-history":[{"count":1,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/posts\/29438\/revisions"}],"predecessor-version":[{"id":29595,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/posts\/29438\/revisions\/29595"}],"wp:attachment":[{"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/media?parent=29438"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/categories?post=29438"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bihec.com\/alphalab\/wp-json\/wp\/v2\/tags?post=29438"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
