Description
The IRT-2000 Automatic Battery Internal Resistance Tester (also designated as model TMAX-R203) is a precision diagnostic instrument engineered to evaluate the internal AC resistance and health of rechargeable batteries. By applying a 1 kHz AC test signal and monitoring the resulting voltage drop using a professional four-wire acquisition method, this device measures milliohm-class impedance accurately—allowing manufacturers, quality control teams, and hobbyists to assess battery performance, aging, and acidification/membrane damage rapidly.
Unlike standard multimeters that measure ohm-class resistance on unpowered objects, the IRT-2000 can test battery impedance on active or unpowered cells alike. It features dual-range voltage and resistance testing, PC connectivity for data logging, audible buzzer alarms, and wide compatibility across diverse battery chemistry types including Lithium-ion, LiPo pouch cells, NiMH, NiCd, and lead-acid storage batteries.
Note: Product design or model markings may vary slightly based on manufacturing batches. Test leads and computer interface cables are included as per standard manufacturer package.
Key Features
- Four-Wire AC Measurement Method: Applies a 1 kHz test signal to measure milliohm-class internal resistance precisely while eliminating lead resistance errors.
- Dual-Range Voltage & Resistance Testing: Features multiple configurable ranges for both voltage (V1: 0–4.999V / V2: 0–29.99V) and resistance (R1: 0.1–200 mΩ / R2: 1–2000 mΩ).
- PC Connectivity & Data Logging: Equipped with computer interface capabilities to facilitate automated testing, data recording, and quality analysis.
- Audible Buzzer Alarm: Integrated buzzer alerts operators during testing sequences or threshold evaluations.
- Wide Battery Chemistry Support: Compatible with lithium-ion, lithium polymer (pouch cells), nickel-metal hydride (NiMH), nickel-cadmium (NiCd), and lead-acid batteries.
- Rapid Performance Assessment: Lower internal resistance directly correlates to higher cell quality and better discharge performance.
Benefits
- Accurate Quality Control: Quickly screen out degraded, damaged, or aged batteries before assembly or deployment.
- Active & Unpowered Testing: Capable of measuring resistance and voltage on live cells with or without external power supplies.
- Professional Precision: Four-wire testing architecture guarantees repeatable milliohm accuracy compared to standard two-probe multimeters.
- Comprehensive Telemetry: Simultaneously verify terminal voltage and internal impedance to form a complete picture of battery health.
Applications
- Battery Manufacturing & QC: Production-line testing for battery pack assemblers and cell manufacturers.
- EV & Solar Energy Storage: Routine diagnostic checks for lead-acid storage banks and maintenance-free UPS batteries.
- R&D and Laboratory Testing: Scientific research units evaluating experimental battery chemistries and core performance.
- RC & Electronics Workshops: Selecting matched LiPo pouch cells and sorting cylindrical 18650/21700 cells by internal resistance.
