Battery Voltage Internal Resistance Tester PBRM-1
Battery Voltage Internal Resistance Tester PBRM-1 with 4-Wire Kelvin Clips, 110V, 100Ω, 1KHz AC Portable 2.8″ TFT Screen Voltmeter, Calibration Custom Sorting Mode for Li-ion/Pb-Acid/AA Car Batteries
Professional Battery Diagnostics
The PBRM-1 utilizes the industry-standard 4-wire AC method to deliver accurate internal resistance measurements (10mΩ/100mΩ/1Ω/10Ω/AUTO ranges) and voltage detection (±110V DC). Its detachable Kelvin clips ensure reliable contact for diagnosing Li-ion, Pb-Acid, Alkaline, and other battery types.
Smart Efficiency Features
- Auto-Sorting Mode: Define voltage/resistance limits to instantly flag defective batteries with PASS/FAIL counters.
- 6-Point Calibration: Maintain long-term accuracy using reference resistors/batteries.
- Intuitive Interface: Navigate settings via directional keys and auto-ranging.
User-Focused Design
- Built-in rechargeable lithium battery
- Auto-shutdown to conserve power
- Clear LCD with measurement values and status indicators
- Ergonomic button layout (Menu/Return/Directional keys)
Critical Protections:
- AC input strictly prohibited
- ±110V DC voltage limit
- Do not touch metal parts during high-voltage tests
- Professional Battery Resistance Tester: Utilize true 4-wire Kelvin measurement (0.1mΩ resolution) to accurately diagnose internal resistance (10mΩ-10Ω range) and voltage simultaneously
- Voltage Internal Resistance Tester: Dual-parameter LCD display for DC voltage (±110V max) and resistance, ideal for Li-ion/Pb-Acid/alkaline batteries
- Battery Capacity Internal Resistance Tester: Assess battery health by measuring internal resistance – a key indicator of capacity – with auto-sorting mode for PASS/FAIL batch screening
- Optimized for Electric Vehicle Lithium Batteries: Portable design with rechargeable lithium battery and detachable Kelvin clips for safe field testing of voltage EV packs
- Safety-Focused Battery Voltage Internal Resistance Tester: Strict ±110V DC max input with AC signal prohibition and auto-shutdown for secure operation
