ET431 Handheld Compact LCR Meter: Enhanced Precision for Component Testing
Fed up with limited frequency ranges or inconsistent accuracy in L/C/R testing? The ET431 delivers 0.2% basic accuracy, 10Hz-200kHz extended test frequency, and 2.8-inch high-def TFT display—perfect for electronics repair, R&D labs, production line screening, and on-site fieldwork!
User-Friendly & Portable Design
Clear Data Visualization: 2.8-inch TFT LCD (5-digit main/sub parameters) shows L/C/R/Z + X/D/Q/theta/ESR at a glance; bilingual (Chinese/English) display adapts to global users.
On-the-Go Reliability: Large-capacity rechargeable lithium battery (8+ hours of continuous use); compact handheld size (fits toolkits); USB 2.0 communication for seamless PC data sync.
3.7V 2000mAh lithium battery; USB Device (supports SCPI protocol); includes charging adapter
Core Advantages
Superior Precision: 0.2% basic accuracy + 10Hz-200kHz wide frequency range captures tiny component variations—critical for high-end R&D and strict quality control.
Versatile Compatibility: Handles electrolytic capacitors, SMD components, inductors, and resistors; temperature compensation ensures stable results in harsh environments.
Portable Efficiency: Handheld design + long battery life fits field repair; USB data sync simplifies report generation for production teams.
User-Centric Upgrades: Multi-level test voltage, adjustable screening limits, and 5-speed measurement adapt to beginners and professional technicians alike.
Applicable Scenarios
Electronics Repair: Test ESR of aged capacitors, inductance of faulty coils, and resistance of precision resistors—pinpoint faults quickly.
Production Lines: Screen components with 0.1%-100% adjustable limits; deviation measurement verifies compliance with nominal values, boosting inspection speed.
R&D Labs: 10Hz-200kHz frequency range analyzes component performance under low-frequency (e.g., audio) and high-frequency (e.g., IoT) scenarios.
Fieldwork: On-site testing of industrial equipment components (e.g., motor inductors, power supply capacitors) without AC power.
All-in-One Functionality: Replaces single-parameter tools—handles L/C/R/ESR testing with one device, saving space and cost.
Complete Accessories: Includes USB cable, charging adapter, short circuit chip, rubber test probes; optional Kelvin clip for SMD component testing.
