Hioki DC resistance meters measure a broad range of resistance values at a high level of precision. The RM3543 is designed to be integrated into current sensing resistor taping machines, deliver high-accuracy measurement of super-low-resistance levels, and are advanced enough to measure 0.1 mΩ shunts with room to spare.
