ZOYI ZT-XR1 2-in-1 4-Wire Battery Internal Resistance Tester and Digital Multimeter
The ZOYI ZT-XR1 is a high-precision 2-in-1 4-wire battery internal resistance tester and True RMS digital voltage meter engineered for evaluating 18650 lithium-ion, LiFePO4, polymer, nickel-metal hydride, and lead-acid battery packs.
- 4-Wire Kelvin Measurement: Uses AC 1kHz 4-terminal sensing to eliminate lead and contact resistance for accurate milliohm readings.
- Wide Resistance & Voltage Range: Measures internal resistance from 0.01mOhm to 200Ohm and DC voltage up to 100V with fast refresh rate.
- Dual Display IPS Screen: Simultaneously shows internal resistance and battery voltage on a high-contrast color LCD screen.
- Built-In Rechargeable Power: Equipped with a long-lasting lithium battery and USB Type-C charging port for portable workshop or field testing.
- Complete Kelvin Probe Kit: Includes 4-wire Kelvin test clips, precision test probes, USB-C charging cable, and protective carry bag.
