GAOTek Milli Ohmmeter Low Resistance Tester

GAOTek milli ohmmeter low resistance tester is a high precision DC resistance tester.




GAOTek milli ohmmeter low resistance tester is a high precision DC resistance tester. It can be used to detect coil, inductance, transformer, motor, relay contact resistance, connector resistance, fuse, cable resistance, printed circuit resistance, welding hole resistance, conductive film, metal flaw detection and so on. It is a low resistance tester with high speed, high precision and high performance. It can meet the quality assurance of production line, import inspection and laboratory measurement, and also can be applied to the test of automatic equipment.
