It delivers a basic accuracy of 0.02% and a resolution of 0.1 μΩ, covering a range from 3 mΩ to 3 MΩ. This makes it ideal for monitoring even slight changes in contact resistance, such as in electric vehicles (EVs), motor and generator windings, or for high-precision cable length measurements.\u003c\/p\u003e\n\u003cp\u003eThe RM3548-50 is compact and lightweight. Weighing less than 1 kilogram, this resistance meter allows for easy use in hard-to-reach places. Its rugged design and portability make it a convenient tool for fieldwork and maintenance tasks. With a high current capability of up to 1 A, it can measure low resistance values reliably, making it suitable for checking continuity in automotive ground lines and inspecting welds in aircraft fuselages.\u003c\/p\u003e\n\u003cp\u003eThe Resistance Meter RM3548-50 features temperature correction, ensuring accurate measurements by adjusting for ambient conditions. It also includes advanced functions like interval measurement, making it suitable for temperature-rise testing. The device requires no warm-up or zero adjustments, allowing for immediate operation.\u003c\/p\u003e\n\u003cp\u003eWith a memory capacity for 1000 data points and easy USB data transfer, the RM3548-50 is highly functional for on-site testing. The resistance meter's overvoltage protection up to 70 V DC and intuitive user interface further enhance its reliability and usability for professionals working in maintenance and testing applications. This four-wire resistance meter combines precision, portability, and ease of use, making it a versatile choice for a wide range of industrial applications.\u003c\/p\u003e\n\u003cp\u003eWhen paired with the optional Z3210 Bluetooth adapter, measurement data can be wirelessly transferred to a smartphone or tablet. A backlit display ensures easy readings even in low-light environments. A variety of optional test leads is available, covering both general measurement applications and specialized ones, such as measuring coated alloys or working in sensitive aircraft environments.\u003c\/p\u003e\n\u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n\u003cp\u003e• RM3548-50 Portable Resistance Meter\u003cbr\u003e• L2107 Clip Type Lead\u003cbr\u003e• Z2002 Temperature Sensor\u003cbr\u003e• Z5041 Instrument Protector\u003cbr\u003e• LR6 Alkaline battery (×8)\u003cbr\u003e• Instruction manual\u003cbr\u003e• USB cable (A to mini-B type)\u003cbr\u003e• Neck strap\u003cbr\u003e• Spare fuse\u003c\/p\u003e\n\u003ch3\u003eRelated Products\u003c\/h3\u003e\n\u003cp\u003e• Z3210 Bluetooth Adapter\u003cbr\u003e• L2140 Test Leads\u003cbr\u003e• L2141 Test Lead\u003cbr\u003e• L2142 Test Lead\u003cbr\u003e• 9465-10 Straight Pin Type Lead\u003cbr\u003e• 9465-11 Pin Type Lead\u003cbr\u003e• 9465-90 Tip Pin (Replacement for 9465-10, 9465-11, L2020, L2140)\u003cbr\u003e• 9772 Straight Pin Type Lead\u003cbr\u003e• 9772-90 Tip Pin (Replacement for 9772, L2003, L2100, L2110)\u003cbr\u003e• 9453 Four Terminal Lead\u003cbr\u003e• L2107 Clip Type Lead\u003cbr\u003e• 9467 Large Clip Type Lead\u003cbr\u003e• 9454 Zero Adjustment Board (for L2100, 9465-10, 9465, 9461)\u003cbr\u003e• L2105 LED Comparator Attachment\u003cbr\u003e• Z2002 Temperature Sensor\u003cbr\u003e• Z5041 Instrument Protector\u003cbr\u003e• C1014 Carrying Case\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Hioki","offers":[{"title":"Default Title","offer_id":58412391137612,"sku":"70025591","price":1183.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/2245\/6652\/files\/Screenshot2026-07-10102920.jpg?v=1786730419","url":"https:\/\/www.testequity.co.uk\/products\/hioki-rm3548-50-70025591","provider":"TestEquity UK","version":"1.0","type":"link"}
