In the test of small resistance, in order to eliminate the error caused by the lead resistance measurement, the ETA4555 uses the Kelvin method four-wire detection, the stylus part is a 4-point telescopic probe, the double-row shape design, and the probe gold plating treatment can stabilize the current passing. Reduces corrosion and intrusion in the environment of the probe to improve durability and wear resistance. The 4mm standard banana plug can be used in instruments with 4-wire resistance measurement functions such as micro-ohm meter, desktop multimeter, battery internal resistance tester, etc. Easy to use in various places such as acceptance inspection.

- Designed for internal resistance measurement for easy handheld measurement

- Four-wire probe detection to eliminate lead errors

- Double row shape design

- Elastic probe telescopic design, gold plating process, low resistance measurement is more stable

- Standard plug compatibility, 4mm full-sheath safety banana plug

- Workmanship, use the mold to suppress the details and deal with excellence
