UNI-T UT204 Digital Clamp Meter The UNI-T UT204 digital clamp meter is a versatile handheld instrument built for electricians, technicians, and DIY enthusiasts who need quick, accurate measurements in electrical circuits without breaking the circuit. Its ergonomic body and intuitive dial layout make it easy to select from multiple measurement functions just by rotating the switch. The meter’s large LCD with backlight improves readability in dim work environments, ensuring users can clearly see readings during troubleshooting and maintenance tasks. Designed with True RMS measurement technology, the UT204 delivers more accurate results on non-sinusoidal AC waveforms compared to basic average-responding meters. It measures current via its clamp jaws (up to 600 A AC/DC on certain variants), allowing safe current checks without direct contact or circuit interruption. It also supports voltage, resistance, continuity, frequency and more, providing a multifaceted testing tool in a single device. The UT204 includes automatic range selection and protective features such as overload prompts, low battery indication and auto shut-off to extend battery life. With a wide jaw opening suitable for many conductor sizes and built-in safety protections up to industry CAT standards, this clamp meter is reliable for both residential and professional electrical work, streamlining measurement tasks across voltage/current diagnostics and general circuit checks. Features: True RMS measurement for accurate AC readings. Auto range capability for simplified operation. Large backlit LCD for visibility in low light. NCV (Non-Contact Voltage) detection. Data hold and MAX/MIN recording. Live/neutral wire test. Auto power-off for energy saving. Low battery indication.
