SB2100 Type Loop Resistance Measuring InstrumentDetailed product description：

The SB2100 circuit resistance measuring instrument is a device developed with advanced foreign technology, suitable for testing the contact resistance of switches in the power industry, high and low voltage switch factories, and other units. The equipment tests digital, constant current, and can work for a long time. It has the function of one click operation and locking in operation. Using the four terminal wiring method, the measurement data at the top of the mast will not damage the current line open circuit or short circuit instrument.
