In order to eliminate the errors caused by lead resistance, ETA4554 adopts four-wire Kelvin method. The probe is a single point telescopic probe. In order to meet the needs of battery testing site, the probe gold plating process can stabilize the passage of current, alleviate the corrosion interference of the probes using environment, improve durability and wear resistance. The 4 mm standard banana plug can be used in the battery testing field. 4-wire resistance measuring instruments, such as micro-ohmmeter, desktop multimeter, battery internal resistance tester, can be easily used in production line, acceptance testing and other fields.

- Designed for measuring internal resistance, convenient for hand-held rapid measurement

- Four-wire Probe Detection Method to Eliminate Lead Error

- Four-line measurement with single axis design, two needles closer

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

- Standard plug compatible, 4mm full sheath safe banana plug

- Pay attention to workmanship, use die pressing details processing and strive for excellence
