Portable design ideal for maintenance and testing of large equipment
CHT3548 DC resistance tester offers a portable solution for measuring resistance with a wide range 0.1μΩ~3.3MΩ at a high level of precision 0.02%. It has a wide application in measurement of ordinary resistors, coil resistance (large motors, transformers, and inductors), cable length and diameter detection, pipe welding and metals detection and electric cars to ground connection detection and so on.
Its ultra-low-power design makes the instrument continuous work for approximately 7 hours in 0.1μΩ measurement range.
Due to the strong surge withstand capability, CHT3548 can be used to test winding resistance of devices.
