Crafted for electronics repair and testing, it helps you quickly determine whether capacitors are good or failing on power supplies, TVs, LCDs, audio boards, and other electronics. This meter uses a true 100 kHz sine wave to measure ESR, effectively removing capacitor impedance for an accurate read. \u003c\/p\u003e \u003cp\u003eIn practice, this means you can reliably test capacitors in-circuit with minimal disturbance to the surrounding circuitry. The device applies less than 15 mV (DC or peak-to-peak) on a good capacitor, enabling safe, in-circuit ESR testing without removing components. Dual terminals, a printed ESR reference table, and an included SMD clip make fast, accurate inspections easy during repairs or diagnostics.\u003c\/p\u003e \u003cp\u003eWhether you are a hobbyist or a professional technician, the MESR100 helps you quickly verify capacitor health during TV, LCD, audio, and board repair projects. Its sturdy copper-plated surface resists corrosion, and the compact 14.5 × 8 × 3 cm body fits comfortably in a tool kit for on-the-go testing. \u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eUse for in-circuit ESR testing to quickly identify bad or failing capacitors in power supplies and signal paths.\u003c\/li\u003e \u003cli\u003eTake advantage of the dual terminal design and SMD clip for fast, accurate testing on through-hole and surface-mount capacitors alike.\u003c\/li\u003e \u003cli\u003eRely on the built-in ESR reference table for quick comparison and faster repairs on TVs, LCDs, and audio boards.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cb\u003eColor:\u003c\/b\u003e Black\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eMeasuring range:\u003c\/b\u003e 0.001–100.0 Ω\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eAccuracy:\u003c\/b\u003e Up to 1% (0.000–1.000 Ω: 1% + 2 digits; 1.000–10.00 Ω: 1% + 1 digit; 10.00–100.0 Ω: 2% + 1 digit)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eHigh resolution:\u003c\/b\u003e 4 digits, 0.001 Ω on the 1 Ω range\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eMeasuring voltage (TESTING VOLTAGE):\u003c\/b\u003e \u0026lt; 40 mV RMS\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eExternal power:\u003c\/b\u003e 5V micro USB\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eOperating current:\u003c\/b\u003e 0.02 A\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eBattery:\u003c\/b\u003e 2 × AA 1.5 V (not included)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eBattery life:\u003c\/b\u003e \u0026gt; 80 hours\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eDisplay type:\u003c\/b\u003e Digital\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eDimensions:\u003c\/b\u003e ~14.5 × 8 × 3 cm (5.7 × 3.1 × 1.2 in)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eWeight:\u003c\/b\u003e ~139.6 g (4.9 oz)\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eIn-circuit testing:\u003c\/b\u003e Yes\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eIncluded features:\u003c\/b\u003e Dual terminal, printed ESR table, SMD clip\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eManufacturer\/brand:\u003c\/b\u003e meterk\u003c\/li\u003e \u003cli\u003e\n\u003cb\u003eCertification:\u003c\/b\u003e CE\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1 × Capacitance Meter\u003c\/li\u003e \u003cli\u003e2 × Test Clips\u003c\/li\u003e \u003cli\u003e1 × SMD Clip\u003c\/li\u003e \u003cli\u003e1 × User Manual\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings\/Reminders\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eNote: The Capacitance Meter is used for testing the internal resistance of the capacitor, not for testing capacitance value.\u003c\/li\u003e \u003cli\u003ePower off the circuit before testing and follow standard safety practices when handling live electronics.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eLanguage support\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003eAvailable languages: English\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eProviding quality and trusted service since 2002 at intercyprus.com.\u003c\/p\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cp\u003ePlease note: All electronic and mechanical equipment, devices and machines sold to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e","brand":"InterCyprus","offers":[{"title":"Set B","offer_id":51478317072726,"sku":"1005005682336059-Set B","price":93.53,"currency_code":"EUR","in_stock":true},{"title":"Set A","offer_id":51478317105494,"sku":"1005005682336059-Set A","price":100.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/S5cfce275b46a44a1afefeae8297b492az.webp?v=1759509721","url":"https:\/\/www.intercyprus.com\/products\/mesr-100-esr-capacitor-tester-ohm-meter-professional-capacitor-capacitance-internal-resistance-measuring-tool-circuit-tester","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
