It offers \u003cstrong\u003efour test voltages from 100 V to 1000 V\u003c\/strong\u003e and measures insulation resistance from \u003cstrong\u003e0.1 MΩ to 20 GΩ\u003c\/strong\u003e with ±(5% + 3 digits) accuracy.\u003c\/p\u003e\u003cp\u003eAlongside standard insulation tests it handles \u003cstrong\u003epolarisation index (PI)\u003c\/strong\u003e, \u003cstrong\u003edielectric absorption ratio (DAR)\u003c\/strong\u003e, timed and continuous measurements, plus AC\/DC voltage measurement. A \u003cstrong\u003ecompare function\u003c\/strong\u003e lets you preset pass\/fail limits with an audible alarm, and \u003cstrong\u003eautomatic discharge\u003c\/strong\u003e safely releases residual charge after each test, backed by high-voltage warning and low-battery indication.\u003c\/p\u003e\u003cp\u003eUp to \u003cstrong\u003e100 results\u003c\/strong\u003e can be stored, and the backlit dual-area display shows resistance, unit, test voltage and time at a glance. It runs on \u003cstrong\u003e8 × AA batteries or a 12 V DC supply\u003c\/strong\u003e.\u003c\/p\u003e","brand":"FNIRSI","offers":[{"title":"Default Title","offer_id":44658277941307,"sku":"EKO-MRT1050","price":145.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/6197\/2795\/files\/mrt1050-insulation-resistance-tester-main.jpg?v=1792606705","url":"https:\/\/ekodeluxe.co.uk\/products\/mrt1050-insulation-resistance-tester","provider":"EkoDeluxe","version":"1.0","type":"link"}
