In the test of small resistance, in order to eliminate the error caused by the lead resistance measurement, the ETA4556 uses the Kelvin method four-wire detection, the stylus part is a 4-point telescopic probe, and the flat shape design is designed to meet the needs of the battery test site. Needle gold plating can stabilize the flow of current and reduce the corrosion intrusion of the probe environment 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-ohmmeter, desktop multimeter, and battery. Resistance tester, etc., can be easily used in various fields such as production line, acceptance inspection, etc.

- Designed for measuring battery internal resistance, convenient for handheld rapid measurement

- Four-wire probe detection to eliminate lead errors

- Flat design four-wire measurement for deep measurement even in narrow areas

- 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
