UNI-T UT216B Digital Clamp Meters
The UNI-T UT216B is a professional-grade True RMS digital clamp meter designed for electricians, maintenance engineers, industrial technicians, and HVAC professionals. It accurately measures AC current up to 600A without disconnecting the circuit while also providing comprehensive voltage, resistance, capacitance, and frequency measurement capabilities.
Features:
- True RMS Ensures accurate measurements on non-linear and distorted AC waveforms.
- Auto Range Automatic scaling with a fast sampling rate of 3 times per second.
- Measurement Modes Supports MAX, MIN, and Relative (REL) modes.
- Flashlight Built-in work light for operating in dark or low-light environments.
- NCV (Non-Contact Voltage) Integrated sensor for safe, non-contact AC voltage testing.
