Rubber-armoured and durable, with automatic discharge, live voltage protection, Megger Intelligent Safety System, colour-coded ranges, and results downloadable to Megger Powersuite Professional. Supplied with 3-year warranty.<\/p>\n<p>The&nbsp;MIT310, MIT320, and MIT330 testers use both digital and analogue displays that&nbsp;simultaneously show the test results numerically, and in the form of a moving-arc bar graph that accurately simulates the operation of an analogue meter. If you&nbsp;prefer a true analogue device, however, Megger is offering the MIT310A which has features similar to those of the MIT310, but with a conventional moving-coil meter movement in place of the digital display.<\/p>\n<p>All products in the MIT300 range&nbsp;offer automatic discharge of the circuit after testing, audible and visual warning if the test probes are applied to a live circuit, and a test inhibit feature which operates automatically under live circuit conditions. The units also conform fully to IEC 61010-1 for use in Category III 600 V applications, and provide all of the facilities needed to meet insulation testing requirements relating to the current edition of the IEE Wiring Regulations.<\/p>\n<p>All instruments in the the MIT300 range provide indication of insulation resistance up to 999 M&Omega;, 200 mA continuity testing, a fast-reacting continuity buzzer, and facilities for nulling the resistance of the test leads. The entry-level MIT300 offers insulation test voltages of 250 V and 500 V, while the remaining models allow testing at 250 V, 500 V, and 1000 V.<\/p>\n<p>In line with other products in Megger&#8217;s comprehensive new contractor range, MIT300 insulation testers feature rugged construction, with an impact-resistant rubber-overmoulded case, and innovative circuitry which guarantees high accuracy combined with stability of calibration.&nbsp;All testers come complete with a full calibration certificate.<\/p>\n<p>In addition to the basic features, the mid-range MIT310 adds a default voltmeter function, while the MIT320 supplements these facilities with an a backlit display, illuminated range panel, insulation limit alarm, resistance measurement, and an adjustable threshold for the continuity buzzer. The MIT320 is also supplied with a switched test probe to speed hands free testing.&nbsp;An illuminated switched test probe is also available as an optional extra for&nbsp;the MIT320.&nbsp;<\/p>\n<ul>\n<li>Extremely easy to use<\/li>\n<li>Tough rubber armoured case<\/li>\n<li>Self contained protective cover<\/li>\n<li>Live circuit warning<\/li>\n<li>Weatherproof to IP54<\/li>\n<li>Intelligent safety system for protection<\/li>\n<\/ul>\n<p>250V Min, 1000V dc Max, 999M&Omega; Max, CAT III 600V<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Megger MIT330 Insulation Tester Megohmmeter<\/p>\n","protected":false},"featured_media":6667,"template":"","meta":{"content-type":""},"product_brand":[],"product_cat":[38],"product_tag":[39],"class_list":["post-6668","product","type-product","status-publish","has-post-thumbnail","product_cat-uncategorized","product_tag-shopify","entry","has-media","first","instock","shipping-taxable","purchasable","product-type-simple","has-product-nav","col","span_1_of_3","owp-content-center","owp-thumbs-layout-horizontal","owp-btn-normal","owp-tabs-layout-horizontal","has-no-thumbnails"],"_links":{"self":[{"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=\/wp\/v2\/product\/6668","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=\/wp\/v2\/media\/6667"}],"wp:attachment":[{"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6668"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_brand&post=6668"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=6668"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/tmgtestequipment.com.au\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=6668"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
