The UNI-T UT251C+ is a high-accuracy true RMS leakage current clamp meter with exceptional measurement sensitivity down to 1µA resolution. Engineered specifically for testing AC leakage current in electrical systems, its large 40mm jaw opening and strong anti-interference capabilities ensure reliable performance even in electrically noisy environments. With advanced features like harmonic measurement, Bluetooth connectivity, and LPF filtering technology, this professional-grade meter delivers the precision and reliability needed by maintenance technicians, electrical safety inspectors, and field service personnel in commercial buildings, industrial facilities, data centers, and residential applications.
 
Precision Leakage Detection for Safety Compliance
The UNI-T UT251C+ delivers exceptional measurement accuracy with its high-resolution design, providing the precision needed for detailed leakage current diagnostics. With current measurement accuracy of ±(1%+5) for 45Hz~60Hz frequency range and resolution down to 1µA, it offers the sensitivity required for detecting even the smallest leakage currents. The True RMS measurement capabilities ensure accurate readings regardless of waveform distortion, while the specialized LPF (Low Pass Filter) function eliminates high-frequency interference for stable and reliable measurements.
The advanced harmonic analysis capability identifies and quantifies harmonic components up to the 20th order, allowing technicians to evaluate power quality issues and troubleshoot complex electrical problems. This feature is particularly valuable when diagnosing equipment malfunctions caused by harmonic distortion or when verifying compliance with power quality standards.
Comprehensive Measurement Capabilities
The UT251C+ combines essential leakage current measurements with specialized functions to deliver complete diagnostic capabilities:
AC current measurement from 3mA to 60A with high resolution
Frequency measurement from 99.99Hz to 5.000kHz with ±(0.1%+5) accuracy
Harmonic analysis of current waveforms up to the 20th order
Maximum/minimum value recording for monitoring variations
Data hold function for convenient reading capture
Auto-ranging for simple operation and accurate measurements
Bright backlit display for visibility in all working conditions
Built-in flashlight for illuminating dark work areas
These comprehensive measurement capabilities make the UT251C+ the ideal tool for professionals who need reliable leakage current detection and analysis in a single instrument.
