UNI-T UT207B Digital Clamp Meter
The UNI-T UT207B is a professional-grade, handheld digital clamp meter designed for electricians and technicians. It is engineered to safely and accurately measure a wide array of electrical parameters in demanding environments. As a True RMS device, it is capable of providing correct readings on non-linear loads, which is essential for diagnosing modern electrical systems. Its robust construction and safety certifications make it a reliable tool for both industrial and residential applications.
The meter features a large LCD display with a clear digital readout and an analog bar graph for tracking trends. Its ergonomic design includes a jaw opening trigger and hand guards for safe, one-handed operation. The intuitive function dial and array of dedicated buttons allow for quick access to various modes like data hold, relative measurement, and backlight. A built-in flashlight and non-contact voltage (NCV) sensor enhance its utility in poorly lit areas, enabling users to quickly check for live wires before proceeding with work.
At its core, the UT207B excels in measuring AC/DC current up to 1000A without breaking the circuit. Beyond current, it measures AC/DC voltage, resistance, capacitance, frequency, and duty cycle. Specialized functions include a Low Pass Filter (LPF) for accurately measuring variable frequency drive (VFD) and inverter outputs by filtering out high-frequency noise, and an inrush current mode to capture the initial startup surge of motors and transformers, which is critical for troubleshooting.
Features:
- True RMS accuracy for correct measurements on non-sinusoidal waveforms.
- Measures AC/DC current (1000A), AC/DC voltage, resistance, capacitance, frequency, duty cycle.
- Inrush current function to capture motor startup surges.
- Low Pass Filter (LPF) for accurate VFD and inverter measurements.
- Non-Contact Voltage (NCV) detection with audible/visual alarm.
- Data Hold, Max/Min, and Relative modes.
- Analog bar graph, backlight, and built-in flashlight.
- High safety rating: CAT IV 600V / CAT III 1000V.
- Low battery indication and auto power-off.
